Bis(?-5-carb-oxy-benzene-1,3-dicarboxyl-ato)-?O,O:O;?O:O,O-bis-[(2-phenyl-1,3,7,8-tetra-aza-cyclo-penta-[l]phenanthrene-?N,N)lead(II)].

ABSTRACT: In the title compound, [Pb(2)(C(9)H(4)O(6))(2)(C(19)H(12)N(4))(2)], the Pb(II) atom is five-coordinated by two N atoms from a chelating 2-phenyl-1H-1,3,7,8-tetra-aza-cyclo-penta-[l]phenanthrene (L) ligand and three O atoms from two Hbtc ligands (H(3)btc is benzene-1,3,5-tricarb-oxy-lic acid), resulting in a distorted PbN(2)O(3) coordination. Two Pb(II) atoms are bridged by the Hbtc ligands, forming a discrete centrosymmetric dinuclear complex. Inter-molecular N-H?O and O-H?O hydrogen bonds and ?-? inter-actions between the pyridine and imidazole rings, and between the pyridyl rings of the L ligands [centroid-centroid distances = 3.600?(6) and 3.732?(6)?Å] lead to a three-dimensional supra-molecular structure.

Project description:In the title complex, [Zn(2)(C(8)H(4)O(4))(C(20)H(11)N(4)O(2))(2)]·4H(2)O, the Zn(II) atom is six-coordinated by two carboxyl-ate O atoms from one bidentate benzene-1,4-dicarboxyl-ate (1,4-BDC) ligand, two carboxyl-ate O atoms from two different monodentate 4-(1H-1,3,7,8-tetra-aza-cyclo-penta-[l]phenanthren-2-yl)benzoate (HNCP) ligands and two HNCP N atoms. The Zn(II) atoms are bridged by the centrosymmetric 1,4-BDC ligands, forming an extended single-chain structure. Neighbouring single chains are connected by the HNCP ligands from two opposite directions, resulting in a sheet. In addition, there are N-H⋯O hydrogen-bonding inter-actions between adjacent layers. As a result, the polymeric sheets are further extended into a three-dimensional supra-molecular structure.

Aqua-(2-hydr-oxy-5-sulfonatobenzoato-?O)bis-(2-phenyl-1H-1,3,7,8-tetra-aza-cyclo-penta-[l]phenanthrene-?N,N)zinc(II).

Project description:In the title compound, [Zn(C(7)H(4)O(6)S)(C(19)H(12)N(4))(2)(H(2)O)], the Zn(II) ion is coordinated by two N,N'-bidentate 2-phenyl-1H-1,3,7,8-tetra-azacyclo-penta-[l]phenanthrene ligands, one O-monodentate 5-sulfosalicylate dianion and a water mol-ecule. This results in a distorted cis-ZnO(2)N(4) octa-hedral coordination geometry for the metal ion. In the crystal, mol-ecules are expanded into a three-dimensional supra-molecular motif via O-H?O, O-H?N and N-H?(O,S) hydrogen bonds. In addition, ?-? stacking inter-actions between the aromatic rings of the polycyclic ligands consolidate the sturcture [shortest centroid-centroid distance = 3.501?(2)?Å].

Poly[diaqua-penta-kis(?(4)-benzene-1,2-dicarboxyl-ato)(?(3)-benzene-1,2-dicarboxyl-ato)tetra-thulium(III)].

Project description:The title compound, [Tm(4)(C(8)H(4)O(4))(6)(H(2)O)(2)](n), has been synthesized hydro-thermally. The asymmetric unit has four unique Tm(III) ions that are six-, seven-, eight- and nine-coordinate. The cations are inter-connected by bridging benzene-1,2-dicarboxyl-ate (BDC) anions to form an infinite two-dimensional framework, in which the BDC ligands adopt three different coordination modes. Adjacent sheets are further packed to form a three-dimensional supra-molecular framework through O-H?O hydrogen bonds.

Poly[[?-1,4-bis-(imidazol-1-ylmeth-yl)benzene]bis-(?(4)-cyclo-hexane-1,4-dicarboxyl-ato)dinickel(II)].

Project description:The structure of the polymeric title compound, [Ni(2)(C(8)H(10)O(4))(2)(C(14)H(14)N(4))](n), features a five-coordinate Ni(II) centre defined by four carboxyl-ate O atoms from two different cyclo-hexane-1,4-dicarboxyl-ate (chdc) ligands and an N atom from one end of a 1,4-bis-(imidazol-1-ylmeth-yl)benzene (1,4-bix) mol-ecule. The NO(4) coordination geometry is distorted square-pyramidal with the N atom in the apical position. Each end of the chdc ligand links pairs of Ni(II) atoms into a paddle-wheel assembly, i.e. Ni(2)(O(2)CR')(4). These are connected into rows owing to the bridging nature of the chdc ligands, and the rows are connected into a two-dimensional grid via the 1,4-bix ligands. The 1,4-bix ligand, which is disposed about a centre of inversion, is disorderd. Two positions of equal occupancy were discerned for the -H(2)C(C(6)H(4))CH(2)- residue.

Poly[[?(2)-1,4-bis-(imidazol-1-ylmeth-yl)benzene]bis-(?(4)-cyclo-hexane-1,4-dicarboxyl-ato)dicobalt(II)].

Project description:In the title compound, [Co(2)(C(8)H(10)O(4))(2)(C(14)H(14)N(4))](n), the two Co(II) atoms are both five-coordinated by four carboxyl-ate O atoms, derived from two different cyclo-hexane-1,4-dicarboxyl-ate (chdc) ligands, and an N atom, derived from one end of a 1,4-bis-(imidazol-1-ylmeth-yl)benzene mol-ecule (1,4-bix), in a distorted square-pyramidal environment. Each end of the chdc ligand links pairs of Co(II) atoms into a paddle-wheel assembly, i.e. Co(2)(O(2)CR')(4); these are connected into rows because of the bridging nature of the chdc ligands, and the rows are further connected into a two-dimensional layer through the 1,4-bix ligands. The 1,4-bix ligand, which is disposed about a centre of inversion, is disorderd. Two positions were discerned for the -CH(2)(C(6)H(4))CH(2)- residue, with the major component having a site-occupancy factor of 0.512?(9).
