metal-organic compounds
In the crystal structure of the title compound, K2[Ni(C16H14N2O2)]6[Ni(CN)4]·6CH3OH·2H2O, at 180 K, the nickel(II)-Schiff base units form dimeric associations across inversion centres. The K+ cations occupy distorted octahedral sites surrounded by O atoms of the nickel(II)-Schiff base units, and the centrosymmetric [Ni(CN)4]2- anions participate in a two-dimensional hydrogen-bond network that includes the uncoordinated methanol and water molecules.

The title vanadium complex, [VClO(C16H22N4)]ClO4, of the tetradentate ligand N,N'-dimethyl-N,N'-bis(2-pyridylmethyl)ethane-1,2-diamine was obtained from air oxidation of a mixture of the ligand and VCl3 in wet methanol.

The title copper complex, [Cu(C2H3O2)(CH4O)(C18H17N3)]PF6, of the tridentate ligand N-phenyl-N,N-bis(2-pyridylmethyl)amine (phbpa), displays a distorted octahedral coordination geometry in which the κ2O,O′-acetate ligand approaches a κO-binding arrangement. One O atom of the acetate group also accepts an O—HO hydrogen bond [OO = 2.654 (2) Å] from a coordinated methanol molecule in a neighbouring complex.

In the crystal structure of meso-1,2-bis(pyridin-2-yl)ethane-1,2-diol, C12H12N2O2, at 180 K, the molecules lie on inversion centres and are linked into ribbons by complementary O—HN hydrogen bonds.
organic compounds
The crystal structure of the title compound, C14H14N2S8, at 180 K contains pairs of molecules related by centres of inversion, arranged in a herringbone-type manner to form layers. Nσ*(S—C) interactions exist between layers.
metal-organic compounds
In the title complex, [Co(NH2CH2CH2NH2)2(NO2)2](IO4), the cations are situated on two sets of inversion centres and are linked by pairs of complementary N—HO hydrogen bonds into columns arranged in an approximately hexagonal manner. The periodate anions can be envisaged as occupying triangular hollows above and below approximate hexagonal close-packed layers of trans-bis(ethylenediamine-κ2N,N′)dinitrocobalt(III) cations.

In the title complex, [Cu2(CHO3)(C36H54N8)](ClO4)3·C2H3N, at 180 K, the triamino caps of the dicopper(II) cryptate are approximately eclipsed and the benzene rings are arranged so as to form three arms of a twisted triskelion motif. The coordination geometry of one Cu atom is trigonal–bipyramidal, while the second resembles more closely a square pyramid. The latter arrangement accommodates a perchlorate anion coordinated loosely to Cu to give a very distorted octahedral geometry. The cryptate complexes adopt an approximately hexagonal close-packed (hcp) arrangement.

In the crystal structure of the title compound, [Co(C14H30N8O4)]Br3, at 180 K, the cationic complexes lie on twofold rotation axes, and bromide anions lie either on twofold rotation axes or in general positions.
