چکیده
In the title compound, [Co(C(4)H(4)O(4))(C(9)H(7)N)(2)(H(2)O)(2)](n), the Co(II) cation, located on an inversion center, is coordinated by two succinate anions, two isoquinoline ligands and two water mol-ecules in a distorted octa-hedral geometry. The succinate anion, located across another inversion center, bridges the Co cations, forming polymeric chains running along the b axis. The partially overlapped arrangement of parallel isoquinoline ring systems of adjacent polymeric chains and the shorter face-to-face distance of 3.402 (6) Å indicates the existence of weak π-π stacking in the crystal structure. Classical intra- and inter-molecular O-H⋯O hydrogen bonding and weak non-classical inter-molecular C-H⋯O hydrogen bonding help to stabilize the crystal structure.

In the title compound, [Co(C(8)H(4)O(4))(C(5)H(8)N(2))(2)](n), each cobalt(II) ion is coordinated by two N and two O atoms in a distorted tetra-hedral geometry. The isophthalate ligands bridge the metal ions to form polymeric zigzag chains extending along the b axis. Weak C-H⋯O inter-actions contribute to the crystal packing stability.

The title compound, [Co(C(8)H(4)O(4))(C(13)H(14)N(2))(2)(H(2)O)(2)](n), was obtained by the reaction of CoCl(2), 4,4'-trimethyl-enedipyridine and terephthalic acid in a 1:1:1 ratio. The octa-hedrally coordinated cobalt ions are bridged by 4,4'-trimethyl-enedipyridine ligands, generating a chain. These chains are further linked by O-H⋯O and O-H⋯N hydrogen bonds, giving a three-dimensional network.

In the title one-dimensional coordination polymer, [Cd(SO(4))(C(5)H(8)N(2))(2)(H(2)O)(2)](n), the Cd(II) atom (site symmetry 2) is coordinated by two sulfate O atoms, two water mol-ecules and two 2-ethyl-imidazole ligands in a distorted cis-CdN(2)O(4) octa-hedral geometry. The water mol-ecules have a cis disposition. The bridging sulfate ions (site symmetry 2) link the Cd(II) ions into a polyme...

In the title crystal structure, [Cd(NCS)(NO(3))(C(11)H(9)N(5))](n), the unique Cd(II) ion is coordinated in a distorted penta-gonal-bipyramidal environment. The axial thio-cyanate ligands act in a μ(1,3)-bridging mode to connect symmetry-related Cd(II) ions into one-dimensional chains along [010]. In addition, there are inter-molecular C-H⋯O contacts between chains.
