Catena-Poly[[diaqua-bis-(2-ethyl-1H-imidazole-?N(3))cadmium]-?-sulfato-?(2)O:O'].

ABSTRACT: 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 polymeric chain extending along [001]. The chains are linked by N-H?O and O-H?O hydrogen bonds. The terminal -CH(3) group of the ligand is disordered over two orientations in a 0.61?(5):0.39?(5) ratio.

Project description:The asymmetric unit of the crystal structure of the title compound, [Cd(2)Cl(4)(C(5)H(8)N(2))(3)](n), contains two Cd(II) cations, three 1-ethyl-1H-imidazole ligands, and four Cl(-) anions. The two Cd(II) atoms have quite different coordination environments: one is octa-hedrally coordinated by four Cl atoms and two N atoms from two 1-ethyl-1H-imidazole ligands, and the second is in a severely distorted fivefold coordination by four Cl atoms and one N atom from a 1-ethyl-1H-imidazole ligand. Adjacent Cd(II) cations are inter-connected alternately by pairs of chloride bridges, generating an infinite step-like chain along the a axis. One ethyl group of the 1-ethyl-1H-imidazole ligand is disordered over two sets of sites with a 0.668?(13):0.332?(13) site-occupancy ratio.

Poly[diaqua-bis-(?(3)-1H-imidazole-4,5-dicarboxyl-ato)(?(2)-sulfato)-diytterbium(III)].

Project description:In the title compound, [Yb(2)(C(5)H(2)N(2)O(4))(2)(SO(4))(H(2)O)(2)](n), the Yb(III) ion is eight-coordinated by four O atoms and one N atom from three imidazole-4,5-dicarboxyl-ate ligands, two O atoms from one SO(4) (2-) anion (site symmetry 2), as well as one O atom of a water mol-ecule, giving a bicapped trigonal-prismatic coordination geometry. The metal coordination units are connected by bridging imidazole-4,5-dicarboxyl-ate and sulfate ligands, generating a heterometallic layer. The layers are stacked along the a axis via N-H?O, O-H?O, and C-H?O hydrogen-bonding inter-actions, generating a three-dimensional framework.

Project description:In the title compound, [Cu(SO(4))(C(2)H(8)N(2))(2)](n), the Cu, S and two O atoms lie on a mirror plane. The Cu atom is in a distorted octa-hedral environment and the ethyl-enediamine ligand is in a gauche conformation. The sulfate dianion is bridging, forming a one-dimensional chain. A two-dimensional net parallel to (001) is generated by N-H?O hydrogen bonding between the chains.

catena-Poly[di-μ3-bromido-bis-[(1-ethyl-1H-imidazole-κN (3))disilver(I)]].

Project description:The asymmetric unit of the title coordination complex, [Ag2Br2(C5H8N2)2] n , comprises a monodentate 1-ethyl-imida-zole ligand, an Ag(+) cation and a μ3-bridging Br(-) anion, giving a distorted tetra-hedral AgNBr3 stereochemistry about the Ag(+) cation [Ag-N = 2.247 (2) Å and Ag-Br = 2.7372 (4)-2.7523 (4) Å]. Two bridging bromide anions generate the dimeric [Ag2Br2(C5H8N)2] repeat unit [Ag⋯Ag = 3.0028 (5) Å], while a third Br(-) anion links the units through corner sharing in an inversion-related Ag2Br2 association [Ag⋯Ag = 3.0407 (4) Å], generating a one-dimensional ribbon step-polymer structure, extending along the c axis.

Diaqua-bis-(4-carb-oxy-2-ethyl-1H-imidazole-5-carboxyl-ato-κN,O)cadmium dihydrate.

Project description:The asymmetric unit of the title compound, [Cd(C(7)H(7)N(2)O(4))(2)(H(2)O)(2)]·2H(2)O, consists of one Cd(II) ion, one 4-carb-oxy-2-ethyl-1H-imidazole-5-carboxyl-ate anion, one coordinated water mol-ecule and one lattice water mol-ecule. The Cd(II) ion lies on a twofold axis, and is hexa-coordinated by four O atoms from water mol-ecules and carboxyl-ate groups and two N atoms from two imidazole rings, in a distorted octa-hedral arrangement. An extensive framework of N-H⋯O and O-H⋯O hydrogen bonds with the participation of coordinated and free water mol-ecules is found in the crystal structure, which contributes to the formation of a three-dimensional structure.

catena-Poly[[diaqua-(1H-imidazo[4,5-f][1,10]phenanthroline)cobalt(II)]-μ-sulfato].

Project description:The Co(II) ion in the title complex, [Co(SO(4))(C(13)H(8)N(4))(H(2)O)(2)](n), has a slightly distorted octa-hedral coordination environment formed by two O atoms from two symmetry-related bridging sulfate ligands, two N atoms from a bis-chelating 1H-imidazo[4,5-f][1,10]phenanthroline (IPL) ligand and two O atoms from coordinated water mol-ecules. The bridging sulfate ligands connect Co(II) ions to form a one-dimensional chain along the b-axis direction. In the crystal structure, inter-molecular O-H⋯O, O-H⋯N and N-H⋯O hydrogen bonds link the chains into a three-dimensional network.

catena-Poly[[diaqua-bis-(3-methyl-pyridine-?N)cobalt(II)]-?-sulfato-?O:O'].

Project description:The environment of the Co(II) ion in the title compound, [Co(SO(4))(C(6)H(7)N)(2)(H(2)O)(2)](n), exhibits an octa-hedral configuration with the two 3-methyl-pyridine ligands lying in cis positions with respect to each other and trans to the two coordinated water mol-ecules. The axial positions are occupied by O atoms of the sulfate ions. Co and S atoms occupy special positions (twofold axis, Wyckoff position 4c). Neighboring Co(II) ions are covalently connected with each other through the sulfate ions, thus creating infinite polymeric chains that run along the c axis. The water mol-ecules are connected with neighboring sulfate ions through strong O-H?O hydrogen bonds. Intra-molecular hydrogen bonds parallel to the propagation direction of the chains stabilize the polymeric chains, and inter-molecular hydrogen bonds between chains connect neighboring chains with each other, thus leading to polymeric double chains.

Diaqua-bis-(1H-imidazole-κN(3))bis-(4-nitro-benzoato-κO(1))cadmium.

Project description:In the centrosymmetric title compound, [Cd(C(7)H(4)NO(4))(2)(C(3)H(4)N(2))(2)(H(2)O)(2)], the Cd(II) atom, located on an inversion center, is coordinated by two N atoms and four O atoms in an octa-hedral geometry. The inter-nal cohesion of the mol-ecule is enhanced by an intra-molecular O-H⋯O hydrogen bond. Inter-molecular O-H⋯O and C-H⋯O hydrogen bonds and π-π contacts [centroid-centroid distance = 3.6549 (2) Å] define two-dimensional networks parallel to (001), which are further connected by weaker C-H⋯O inter-actions into a weakly connected three-dimensional supra-molecular framework.

catena-Poly[[bis-(1-ethyl-1H-imidazole-κN)copper(II)]-μ-oxalato-κO,O:O,O].

Project description:The title compound, [Cu(C(2)O(4))(C(5)H(8)N(2))(2)](n), is composed of one-dimensional linear chains running parallel to the a axis. In the chain, trans-[Cu(imidazole)(2)](2+) units are sequentially bridged by bis-bidentate oxalate ligands, resulting in an octa-hedral CuO(4)N(2) donor set. The Cu⋯Cu separation through the oxalate bridge is 5.620 (5) Å. Both the Cu atoms and the C-C bond of the oxalate bridge are bis-ected by inversion centres.

catena-Poly[[[diaqua-cadmium(II)]-bis-[μ-3,5-bis-(isonicotinamido)benzoato]] tetra-hydrate].

Project description:The title compound, {[Cd(C(19)H(13)N(4)O(4))(2)(H(2)O)(2)]·4H(2)O}(n) or {[Cd(BBA)(2)(H(2)O)(2)]·4H(2)O}(n), where BBA is 3,5-bis-(iso-nicotin-amido)-benzoate, is isotypic with its Mn isologue [Chen et al. (2009 ▶). J. Coord. Chem.62, 2421-2428]. The cation sits on a twofold axis and is six-coordinated in a slightly distorted octa-hedral geometry; the polyhedra are linked into zigzag chains, which are further connected by N-H⋯O, O-H⋯O and O-H⋯N hydrogen bonds as well as π-π inter-actions [centroid-centroid distance of 3.639 (2) Å], giving a three-dimensional supra-molecular framework.
