[(1R,4S)-(+)-3-Benzoyl-1,7,7-trimethylbicyclo[2.2.1]heptan-2-olato-κ2 O 2,O 3](η4-norbornadiene)rhodium(I)
2010
In the title complex mol-ecule, [Rh(C(17)H(19)O(2))(C(7)H(8))], the rhodium(I) metal centre is coordinated by the O atoms of a benzoyl-camphorate anion and the C=C bonds of the norbornadiene mol-ecule into a slightly distorted square-planar coordination geometry. The six-membered chelate ring is essentially planar (r.m.s. deviation = 0.0378 Å) and forms a dihedral angle of 31.67 (11)° with the phenyl ring.
[2,6-Bis(di-tert-butylphosphinomethyl)phenyl-κ3P,C1,P′](trifluoroacetato)palladium(II)
2010
The Pd(II) atom in the title compound, [Pd(C(2)F(3)O(2))(C(24)H(43)P(2))], adopts a distorted square-planar geometry with the P atoms in a trans arrangement, forming two five-membered chelate rings. Four intra-molecular C-H⋯O hydrogen bonds occur. The crystal packing reveals one weak inter-molecular C-H⋯O hydrogen bond, which self-assembles the mol-ecules into infinite chains parallel to the b axis.

2007
In the crystal structure of the title complex, [Pt(C5H4NOS)2], the Pt atom is coordinated by two O atoms and two S atoms in a cis configuration, forming a distorted square-planar coordination geometry. The molecule exhibits pseudo-C2v symmetry and is essentially planar, with a maximum deviation from planarity of 0.0124 (2) Å. The dihedral angle between the two pyridine rings is 5.85 (2)°.
cis-Dichloridobis(2-isocyanophenyl 4-methoxybenzoate)palladium(II) chloroform monosolvate
2012
In the title compound, [PdCl2(C15H11NO3)2]·CHCl3, the PdII atom adopts a slightly distorted square-planar coordination geometry composed of two Cl atoms in cis positions and two C atoms from isocyanophenyl ligands. The molecular conformation is stabilized by π–π stacking interactions [shortest centroid–centroid distance = 3.600 (1) Å] between substituted benzene rings of different ligands. The crystal packing is characterized by C—H...O and C—H...Cl interactions involving the chloroform solvent molecules.
Di-chlorido-[N-(N,N-di-methyl-carbamimido-yl)-N',N',4-tri-methyl-benzohydrazonamide]-platinum(II) nitro-methane hemisolvate.
2014
In the title compound, [PtCl2(C13H21N5)]·0.5CH3NO2, the PtIIatom is coordinated in a slightly distorted square-planar geometry by two Cl atoms and two N atoms of the bidentate ligand. The (1,3,5-triazapentadiene)PtIImetalla ring is slightly bent and does not conjugate with the aromatic ring. In the crystal, N—H...Cl hydrogen bonds link the complex molecules, forming chains along [001]. The nitromethane solvent molecule shows half-occupancy and is disordered over two sets of sites about an inversion centre.
Bis(4-aminopyridinium) tetrachloridocobaltate(II)
2009
In the title compound, (C(5)H(7)N(2))(2)[CoCl(4)], the cobalt(II) ion is coordinated by four chloride ions in a slightly distorted tetra-hedral geometry. The crystal packing is stabilized by inter-molecular N-H⋯Cl hydrogen bonding, forming a three-dimensional network. The crystal was a non-merohedral twin emulating tetra-gonal symmetry, but being in fact ortho-rhom-bic.
{2-[2,2-Bis(4,4-dimethyl-4,5-dihydro-1,3-oxazol-2-yl- κN)propyl]pyridine}dichloridoiron(II)
2013
The title compound,[FeCl2(C18H25N3O2)], has a distorted tetra-hedral Cl2N2 coordination of the Fe(II) atom as a result of the constraints imposed by the 2-[2,2-bis-(4,4-dimethyl-4,5-di-hydro-1,3-oxazol-2-yl)prop-yl]pyridine ligand. The pyridine ring is almost perpendicular to the six-membered chelated ring containing the metal atom [dihedral angle between their mean planes = 88.5 (1)°].
(μ-Acetato-κ2 O:O′)[μ-2,6-bis({bis[(pyridin-2-yl-κN)methyl]amino-κN}methyl)-4-methylphenolato-κ2 O:O](methanol-κO)dizinc bis(perchlorate)
2014
The binuclear title complex, [Zn2(C33H33N6O)(CH3COO2)(CH3OH)](ClO4)2, was synthesized by the reaction between 2,6-bis({[bis(pyridin-2-yl)methyl]amino}methyl)-4-methylphenol (H-BPMP), Zn(OAc)2and NaClO4. The two ZnIIions are bridged by the phenolate O atom of the octadentate ligand and the acetate group. An additional methanol ligand is terminally coordinated to one of the ZnIIions, rendering the whole structure unsymmetric. Other symmetric dizinc complexes of BPMP have been reported. However, to the best of our knowledge, the present structure, in which the two ZnIIions are distinguishable by the number of coordinating ligands and the coordination geometries (octahedral and square-pyramidal…
Diammine{N-[2-(hydroxyimino)propionyl]-N′-[2-(oxidoimino)propionyl]propane-1,3-diaminido-κ4N,N′,N′′,N′′′}iron(III)
2012
In the title compound, [Fe(C9H13N4O4)(NH3)2], the Fe(III) atom, lying on a mirror plane, is coordinated by four N atoms of a triply deprotonated tetra-dentate N-[2-(hy-droxy-imino)-propion-yl]-N'-[2-(oxidoimino)-propion-yl]propane-1,3-diaminide ligand in the equatorial plane and two N atoms of two ammonia mol-ecules at the axial positions in a distorted octa-hedral geometry. A short intra-molecular O-H⋯O hydrogen bond between the cis-disposed oxime O atoms stabilizes the pseudo-macrocyclic configuration of the ligand. In the crystal, mol-ecules are linked by N-H⋯O hydrogen bonds into a three-dimensional network. The ligand has a mirror-plane symmetry. One of the methyl-ene groups of the pro…
Pyridinium bis(pyridine-κN)tetrakis(thiocyanato-κN)ferrate(III) -pyrazine-2-carbonitrile-pyridine (1/4/1)
2013
In the title compound, (C5H6N)[Fe(NCS)4(C5H5N)2]·4C5H3N3·C5H5N, the Fe(III) ion is located on an inversion centre and is six-coordinated by four N atoms of the thio-cyanate ligands and two pyridine N atoms in a trans arrangement, forming a slightly distorted octa-hedral geometry. A half-occupied H atom attached to a pyridinium cation forms an N-H⋯N hydrogen bond with a centrosymmetrically-related pyridine unit. Four pyrazine-2-carbo-nitrile mol-ecules crystallize per complex anion. In the crystal, π-π stacking inter-actions are present [centroid-centroid distances = 3.6220 (9), 3.6930 (9), 3.5532 (9), 3.5803 (9) and 3.5458 (8) Å].
