In the title compound, [Cu(C14H12N2)2]C24H20B·CH2Cl2, CuI is chelated by two 2,9-dimethyl-1,10-phenanthroline (2,9-Me2phen) ligands, in a distorted tetrahedral coordination geometry. The average Cu—N bond length is 2.032 Å, and the interligand dihedral angle is 77.60 (6)°. The complexes form π–π stacking interactions between 2,9-Me2phen ligands, with a perpendicular interplanar separation of 3.652 (5) Å.

In the title complex, [Cu(C8H4O4)(C10H9N3)] n , the benzene-1,4-dicarboxylate dianions bridge the CuII atoms to form polymeric complex chains. The CuII atom has a distorted octahedral coordination geometry. The centroid-to-centroid separation of 3.932 (2) Å indicates π–π stacking between nearly parallel pyridine rings.

In the crystal structure of the title compound, [Ni(C5H5N2O2S)2(H2O)], the NiIIcation is located on a twofold rotation axis and chelated by two 2-amino-1,3-thiazole-4-acetate (ata) anions in the basal coordination plane; a water molecule located on the same twofold rotation axis completes the distorted square-pyramidal coordination geometry. Intermolecular O—H...O and N—H...O hydrogen bonding, as well as π–π stacking between parallel thiazole rings [centroid–centroid distance 3.531 (8) Å], helps to stabilize the crystal structure.

Centrosymmetric Dimers

Four imidazo[2,1-b][1,3,4]thiadiazoles containing a simply-substituted 6-aryl group have been synthesized by reaction of 2-amino-1,3,4-thiadiazoles with bromoacetylarenes using microwave irradiation and brief reaction times. 6-(2-Chlorophenyl)imidazo[2,1-b][1,3,4]thiadiazole, C10H6ClN3S, (I), 6-(2-chlorophenyl)-2-methylimidazo[2,1-b][1,3,4]thiadiazole, C11H8ClN3S, (II), 6-(3,4-dichlorophenyl)imidazo[2,1-b][1,3,4]thiadiazole, C10H5Cl2N3S, (III), and 6-(4-fluoro-3-methoxyphenyl)-2-methylimidazo[2,1-b][1,3,4]thiadiazole, C12H10FN3OS, (IV), crystallize withZ′ values of 2, 1, 1 and 2 respectively. The molecular skeletons are all nearly planar and the dihedral angles between the imidazole and aryl rings are 1.51 (8) and 7.28 (8)° in (I), 9.65 (7)° in (II), 10.44 (8)° in (III), and 1.05 (8) and 7.21 (8)° in (IV). The molecules in (I) are linked by three independent C—H...N hydrogen bonds to form ribbons containing alternatingR22(8) andR44(18) rings, and these ribbons are linked into a three-dimensional array by three independent π-stacking interactions. Both (II) and (III) contain centrosymmetric dimers formed by π-stacking interactions but hydrogen bonds are absent, and the molecules of (IV) are linked into centrosymmetricR22(8) dimers by C—H...N hydrogen bonds. Comparisons are made with a number of related compounds.

In the title coordination polymer, [MnCl2(C7H5NS)2]n, the MnIIion is located on the intersection of a twofold rotation axis and a mirror plane and adopts an octahedral coordination geometry defined by two mutuallytransN atoms from benzothiazole ligands which occupy the axial positions, and four Cl atoms which form the equatorial sites. The MnIIions are connected by two bridging Cl atoms, forming chains parallel to thecaxis. The crystal packing can be descibed as alternating layers parallel to (001) featuring π–π stacking interactions with a centroid–centroid distance of 3.6029 (15) Å.
