Crystal structure of the tetraaquabis(thiocyanato-kappa N)cobalt(II)-caffeine-water (1/2/4) co-crystal
In the structure of the title compound, [Co(NCS)2(H2O)4]·2C8H10N4O2·4H2O, the cobalt metal lies on an inversion centre and is coordinated in a slightly distorted octahedral geometry. In the crystal, the complex molecules interact with the caffeine molecules through O—H⋯N, O—H⋯O, C–H⋯S hydrogen bonds and π–π interactions.
Tris(1,10-phenanthroline-κ2N,N′)nickel(II) bis(hexafluoridophosphate)
The asymmetric unit of the title compound, [Ni(C36H24N6)3](PF6)2, contains one and a half nickel(II) complex dications and three hexafluoridophosphate anions, one of the dications having crystallographic twofold rotational symmetry. Each NiIIatom displays a distorted octahedral coordination geometry provided by the six N atoms of three bidentate 1,10-phenanthroline ligands with bite angles of 79.68 (11)–80.76 (12)°. In the crystal, C—H...F hydrogen bonds link the anions and dications into a three-dimensional supramolecular framework. Within the framework complex dications with twofold rotational symmetry are linked by weak π–π stacking interactions [centroid-to-centroid distances = 3.712 (2…
