The title compound is a new ionic complex, (C13H13ClN)[Ni(C4N2S2)2] or [ClBzPyMe][Ni(mnt)2] [where ClBzPyMe is 1-(2-chlorobenzyl)-2-methylpyridinium and mnt is maleonitriledithiolate]. In the anion the NiIII atom is coordinated by the four S atoms of two mnt2− ligands and exhibits the expected square-planar coordination geometry. In the [ClBzPyMe]+ cation the benzene and pyridine rings are twisted with respect to the C/C/N plane incorporating the methylene C atom that links them. The [Ni(mnt)2]− anions and [ClBzPyMe]+ cations stack into well segregated columns along the a axis, and the NiIII ions form a one-dimensional zigzag chain through weak Ni...S, S...S, and π–π interactions.

The title compound, (C12H12BrN2)[Ni(C4N2S2)2], is an ion-pair complex, isostructural with the Cl-containing analogue. The anion lies on an inversion centre and the NiII ion is coordinated by four S atoms, giving the expected square-planar coordination geometry. The cation adopts a conformation where the benzene and pyrazine rings are twisted with respect to the plane of the central C—C—N chain which links them. C—H...S and π–π interactions between cations and anions are observed in the crystal structure, and C—H...π interactions mediate the formation of ribbons of cations.

In the title compound, {[Cu(C14H8O5)(C14H8N4)]·H2O} n , the CuII atom adopts a distorted cis-CuN2O2 square-planar coordination geometry. 4,4′-Oxydibenzoate (L) ligands link the CuII atoms, generating a helical chain. Neighbouring chains are linked through π–π interactions between pyrazino[2,3-f][1,10]phenanthroline ligands with a centroid–centroid distance of ca 3.44 Å, resulting in a two-dimensional supramolecular structure. The structure is completed by O—H...O hydrogen bonds.

The Mean

In the mononuclear title complex, [Co(N3)2(C12H8N4S)2], the cobalt(II) atom is located on an inversion centre and displays an axially weakly compressed octahedral coordination geometry. The equatorial positions are occupied by the N atoms of two 2,5-bis(pyridin-2-yl)-1,3,4-thiadiazole ligands, whereas the axial positions are occupied by N atoms of the azide anions. The thiadiazole and pyridine rings linked to the metal are almost coplanar, with a maximum deviation from the mean plane of 0.0273 (16) Å. The cohesion of the crystal is ensured by weak C—H...N hydrogen bonds and by π–π interactions between pyridine rings [intercentroid distance = 3.6356 (11) Å], forming a layered arrangement parallel to (001). The structure of the title compound is isotypic with that of the analogous nickel(II) complex [Laachiret al.(2013).Acta Cryst.E69, m351–m352].
