2014
The title compound {Co(CO)3[Ph2PN(i-Pr)P(Ph)N(H)i-Pr]}[Co(CO)4] is an ionic species consisting of a Co(CO)3[Ph2PN(i-Pr)P(Ph)N(H)i-Pr] cation and a [Co(CO)4] anion.
Crystal structure of (2E)-3-[4-(dimethylamino)phenyl]-1-(thiophen-2-yl)prop-2-en-1-one
2017
In the title chalcone-thiophene derivative, the dihedral angle between the aromatic and the thiophene rings is 11.4 (2)°. In the crystal, molecules are linked by C—H⋯O and C—H⋯S weak interactions along [100], forming rings of R22(8) graph-set motif, by C—H⋯O weak interactions along [010], forming C(6) chains, and by weak H(methyl–group)⋯Cg(thiophene ring) interactions into dimers; the crystal packing resembles a herringbone arrangement when viewed along [100]. A molecular docking calculation of the title compound with the neuraminidase enzyme was carried out.
Crystal structure of 5-benzyl-8-bromo-2-methyl-1,3-oxazolo[4,5-c][1,8]naphthyridin-4(5H)-one
2017
The structure of an oxazolonaphthyridinone derivative unexpectedly formed during the synthesis of pyridodiazepinediones is reported.
Crystal structure and Hirshfeld surface analysis of 3-octyl-4-oxo-2,6-bis(3,4,5-trimethoxyphenyl)piperidinium chloride
2018
The title compound was synthesized by a one-pot Mannich condensation reaction. In the crystal, centrosymmetric dimers are linked into layers parallel to (011) by N—H⋯Cl and C—H⋯Cl hydrogen bonds. A Hirshfeld surface analysis indicates that O—H (20.5%) interactions make the largest contribution to the crystal packing.

2021
The complex nickel(II) anion comprises a pseudomacrocyclic hydrazide-based ligand with an L shape. In the crystal, such anions are connected with the potassium cations and the water solvent molecules, forming a three-dimensional polymeric framework, which is stabilized by an extensive system of hydrogen bonds.
Crystal structure ofcis-1-phenyl-8-(pyridin-2-ylmethyl)dibenzo[1,2-c:2,1-h]-2,14-dioxa-8-aza-1-borabicyclo[4.4.0]deca-3,8-diene
2017
The present work describes the synthesis and crystal structure of the new B-phenyloxazaborocine, C26H23BN2O2. The title compound adopts a zwitterionic form with a significant intramolecular N→B dative bond and intermolecular C—H⋯O interactions connecting molecules parallel to the b axis.
Crystal structure of the bis(cyclohexylammonium) succinate succinic acid salt adduct
2015
The title salt adduct comprises two cyclohexylammonium cations, one succinate anion and one molecule of succinic acid, linked together through intermolecular hydrogen-bonding interactions giving a two-dimensional layer-like self-assembly lying parallel to (010).
Crystal structure of bis-(azido-κN)bis[2,5-bis(pyridin-2-yl)-1,3,4-thia-diazole-κ(2) N (2),N (3)]cobalt(II).
2015
The structure of the title compound is isotypic with that of the analogous nickel(II) complex, in which the CoN6 core shows an axially weakly compressed octahedral geometry as opposed to the almost regular geometry exhibited by the NiN6 octahedron.
Crystal structure of the diglycidyl ether of eugenol
2017
The diepoxy monomer (DGE-Eu) was synthesized from eugenol by a three-step reaction. It consists of a 1,2,4-trisubstituted benzene ring substituted by diglycidyl ether, a methoxy group and a methyloxirane group. The three-membered oxirane rings are inclined to the benzene ring by 61.0 (3) and 27.9 (3)°. In the crystal, molecules are linked by C—H⋯O hydrogen bonds, forming layers parallel to the ab plane.
