ABSTRACT: One of the two 1,4-dicarboxyl-ate dianions in the title compound, [Mn(2)(C(12)H(6)O(4))(2)(C(19)H(12)N(4))(2)]·C(3)H(7)NO, uses its two carboxyl-ate groups to chelate two N-heterocycle-chelated Mn atoms; the other 1,4-dicarboxyl-ate dianion binds to four such metal centers. The octa-hedrally coordinated Mn atoms are linked through the two dianions into a layer motif; the dimethyl-formamide mol-ecules occupy the spaces between adjacent layers. Ten C atoms and attached H atoms of one dianion are disordered equally over two positions.

Project description:In the crystal structure of the title compound, [Mn(C(12)H(6)O(4))(C(10)H(8)N(2))](n), the Mn atoms are each coordinated by four O atoms of naphthalene-1,4-dicarboxyl-ate anions and two N atoms of two symmetry-related 4,4'-bipyridine ligands within a strongly distorted octa-hedra. Two of the O atoms originate from one naphthalene-1,4-dicarboxyl-ate anion, whereas the remaining two O atoms derive from two symmetry-equivalent naphthalene-1,4-dicarboxyl-ate anions. Two Mn atoms are connected via the anions into dimers, which are further linked by the anions and the N-donor ligands into a three-dimensional coordination network.

Project description:The crystal structure of the title compound, [Ho(2)(C(12)H(6)O(4))(3)(H(2)O)(6)](n), contains binuclear centrosymmetric {Ho(2)O(2)(CO(2))(4)(H(2)O)(6)} cores inter-connected via the naphthalene-2,6-dicarboxyl-ate (NDC(2-)) bridging ligands into a two-dimensional neutral plane net, ∞(2)[Ho(2)(NDC)(3)(H(2)O)(6)], exhibiting a typical (4,4)-topology. Inter-actions between adjacent layers are assured by a series of C-H⋯π contacts and a number of strong and highly directional O-H⋯O hydrogen bonds involving the coordinated water mol-ecules and neighbouring coordinated carboxyl-ate groups. One NDC(2-) bridging ligand has its centroid located at a crystallographic centre of inversion.

Project description:In the title compound, [Pd(C(8)H(4)O(4))(C(7)H(6)N(2))(2)](n), the Pd atom is tetra-coordinated by two carboxyl-ate O atoms from two benzene-1,4-dicarboxyl-ate (bdc) dianions and two N atoms from two benzimidazole ligands, resulting in a slightly distorted tetra-hedral PdO(2)N(2) geometry.

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.
