Zinc Cation

In the title complex, [Zn(C7H4NO3S)2(C8H22N4)]·H2O or [Zn(sac)2(paen)]·H2O [sac = saccharinate and paen = N,N′-bis(3-aminopropyl)ethylenediamine], the zinc cation is octahedrally coordinated. The equatorial plane of the octahedron is formed by N atoms of the paen ligand, whereas the axial positions are occupied by the carbonyl O atoms of the two sac ligands. One of the sulfonyl groups of the sac ligands shows disorder and was modelled with two different orientations and site occupancies of 0:38 (1):0.62 (1). The molecular packing is stabilized by intermolecular O—H...O and N—H...O hydrogen bonds between water molecules and neighbouring [Zn(sac)2(paen)] molecules, which form chains running parallel to [010]. The crystal used was an inversion twin.

In the title complex, [Zn(C12H6N2O4)(H2O)2] n , the Zn atom, located on a twofold axis, is six-coordinated in a distorted octahedral arrangement, with two N atoms and two O atoms of two symmetry-related 2,2′-bipyridine-3,3′-dicarboxyate (dcbp) ligands located in the equatorial plane, while the two O atoms of the water molecules occupy the axial positions. The dcbp ligand acts as a bridging ligand, linking adjacent Zn ions and forming a one-dimensional infinite chain parallel to the b axis. O—H...O hydrogen bonds involving the coordinated water molecules connect adjacent chains to form layers parallel to the (001) plane.

Accuracy And Precision

The crystal structure of the title complex, [Pb3(C4H7O2)6(H2O)2] n , was redetermined on basis of modern CCD-based single-crystal X-ray data at 120 K. The current study basically confirms the previous report [Fallon et al. (1997). Polyhedron, 16, 19–23] at 190 K, but with higher accuracy and precision. In particular, positional disorder of one of the 2-methylpropanoate anions over two sets of sites was resolved, showing a refined ratio of the disorder components of 0.535 (9):0.465 (9). The three independent cations in the structure have coordination numbers of [7 + 1], [6 + 1], and [5 + 3], with O atoms belonging either to carboxylate groups or water molecules. This arrangement leads to the formation of sheets parallel to (\overline{1}01), whereby the hydrophobic 2-methylpropanyl groups of the anions are oriented above and below the hydrophilic sheets to form a layered structure. Within a sheet, hydrogen bonds of the type Owater—H...O are formed, whereas the hydrophobic groups between adjacent layers interact through van der Waals forces.

In the title complex polymer, [Sr(C10H7N6)2(H2O)2]n, the SrIIatom lies on an inversion centre and is coordinated by four N atoms from two bidentate bridgingtrans-related 5-[4-(1H-imidazol-1-yl)phenyl]tetrazolide ligands [Sr—N = 2.387 (4) Å for the tetrazolide moiety and Sr—N = 2.273 (5) Å for the imidazole moiety], and by two O atoms from water molecules [Sr—O = 2.464 (4) Å], giving a distorted octahedral coordination. Pairs of ligand bridges link the complex units, forming chains which extend along [111] and are inter-associated through Owater—H...N hydrogen bonds, giving a two-dimensional network structure parallel to (001). Weak π–π stacking interactions between the benzene and imidazole rings are also present [minimum ring centroid separation = 3.691 (4) Å].

The title complex, [Co(C2N3)2(C7H6N4)2(H2O)2] or [Co(dca)2(pytrz)2(H2O)2], where pytrz is 4-(2-pyridyl)-4H-1,2,4-triazole and dca is the dicyanamide monoanion, was prepared using pytrz, Na(dca) and CoCl2·6H2O. The CoII atom lies on a center of inversion and is coordinated in a slightly distorted octahderal geometry by two pytrz ligands, two dca ligands and two trans-oriented water molecules. In the crystal structure, complex molecules are linked by O—H...N hydrogen bonds into a two-dimensional network and further into a three-dimensional network via weak C—H...N hydrogen bonds.
