Catena-Poly[[[aqua-(1,10-phenanthro-line)manganese(II)]-μ-adamantane-1,3-dicarboxyl-ato] monohydrate].

ABSTRACT: In the title coordination polymer, {[Mn(C(12)H(14)O(4))(C(12)H(8)N(2))(H(2)O)]·H(2)O}(n), the Mn(II) atom has a highly distorted cis-MnN(2)O(4) octa-hedral geometry arising from its coordination by a bidentate phenanthroline ligand, a water mol-ecule and monodentate and bidentate adamantane-1,3-dicarboxyl-ate dianions. The bridging dianion leads to [001] chains in the crystal. The chains are linked by O-H⋯O hydrogen bonds, involving both the coordinated and uncoordinated water mol-ecules, thereby forming a two-dimensional network.

Project description:The asymmetric unit of the title complex, [Mn(C(12)H(6)O(4))(H(2)O)](n), contains one Mn(II) ion, one 1,8-naphthalene-dicarboxyl-ate (1,8-NDC) ligand and one water mol-ecule. The Mn(II) ion is six-coordinated within a distorted octa-hedral coordination geometry, in which the equatorial sites are occupied by four carboxyl-ate O atoms from four different 1,8-NDC ligands, while the axial positions are occupied by two O atoms of two coordinated water mol-ecules. Adjacent Mn(II) centres are bridged by one coordinated water and two carboxyl-ate groups in a syn-syn mode to form infinite chains along the b axis, which are further cross-linked by the naphthalene spacers of the 1,8-NDC ligands to produce a two-dimensional extended network.

Poly[piperazinediium [[aqua-bismuth-ate(III)]-di-μ-pyridine-2,6-dicarboxyl-ato-bis-muthate(III)-di-μ-pyridine-2,6-dicarboxyl-ato] monohydrate].

Project description:The title compound, {(C(4)H(12)N(2))[Bi(2)(C(7)H(3)NO(4))(4)(H(2)O)]·H(2)O}(n) or {(pipzH(2))[Bi(2)(pydc)(4)(H(2)O)]·H(2)O}(n), where pydcH(2) is pyridine-2,6-dicarboxylic acid and pipz is piperazine, was obtained by reaction of Bi(NO(3))(3)·5H(2)O with (pipzH(2))(pydc-H)(2)·3H(2)O in a 1:2 molar ratio in aqueous solution. There are two independent Bi(III) atoms in the structure, one of which is eight-coordinate with a distorted bicapped trigonal-prismatic geometry, and another which is nine-coordinate with a distorted tricapped trigonal-prismatic geometry. The carboxyl-ate groups of the (pydc)(2-) ligands link dinuclear [Bi(2)(C(7)H(3)NO(4))(4)(H(2)O)](2-) units into one-dimensional coordin-ation polymers. The pipzH(2) (2+) cations (site symmetry ) and non-coordinated water mol-ecules lie between these polymers, forming N-H⋯O and O-H⋯O hydrogen bonds to the O atoms of the carboxylate groups.

catena-Poly[[aqua-(1,10-phenanthroline)cadmium(II)]-μ-benzene-1,4-di-carboxyl-ato].

Project description:The title compound, [Cd(C(8)H(4)O(4))(C(12)H(8)N(2))(H(2)O)](n), is a new coordination polymer of benzene-1,4-dicarboxyl-ate with cadmium(II) and 1,10-phenanthroline. The Cd(II) ion is coordinated by two N atoms from the 1,10-phenanthroline mol-ecule, three O atoms from two crystallographically independent benzene-1,4-dicarboxyl-ate ligands and the O atom of a coordinated water mol-ecule, forming a heavily distorted octa-hedron. The 1,10-phenanthroline ligand is approximately planar within 0.073 (4) Å. The two different benzene-1,4-dicarboxyl-ate ligands each coordinate to two Cd(II) ions in bidentate and monodentate modes, forming an infinite zigzag chain. Adjacent chains are packed tightly by strong π-π inter-actions [centroid-centroid distances = 3.851 (2) and 3.859 (2) Å] between the aromatic rings of the benzene-1,4-dicarboxyl-ate ligand and the 1,10-phenanthroline of a neighboring chain, forming a sheet parallel to (011). Different sheets are linked together via O-H⋯O hydrogen bonds between the coordinated water mol-ecules and the O atoms of the carboxyl-ate groups, forming a three-dimensional network.

Project description:The asymmetric unit of the title compound, {[CoEr(2)(C(5)H(2)N(2)O(4))(2)(SO(4))(2)(H(2)O)(4)]·H(2)O}(n), contains a Co(II) ion, two Er(III) ions, two imidazole-4,5-dicarboxyl-ate (imdc) ligands, two SO(4) (2-) anions, four coordinated water mol-ecules and one uncoordinated water mol-ecule. The Co(II) ion is six-coordinated by two O atoms from two coordinated water mol-ecules and two O atoms and two N atoms from two imdc ligands in a slightly distorted octa-hedral geometry. Both Er(III) ions are eight-coordinated in a bicapped trigonal-prismatic coordination geometry. One Er(III) ion is coordinated by four O atoms from two imidazole-4,5-dicarboxyl-ate ligands, three O atoms from three SO(4) (2-) anions and one water O atom; the other Er(III) ion is bonded to five O atoms from three imdc ligands, two O atoms from two SO(4) (2-) anions as well as one coordinated water mol-ecule. The coordinated metal units are connected by bridging imdc ligands and sulfate ions, generating a two-dimensional heterometallic layer. The two-dimensional layers are stacked along the b axis via N-H⋯O, O-H⋯O and C-H⋯O hydrogen-bonding inter-actions between water mol-ecules, SO(4) (2-) anions, and imdc ligands, generating a three-dimensional framework.
