چکیده
In the title mononuclear complex, [Mn(C(8)H(7)O(2))(4)(C(10)H(8)N(2))], the Mn(II) atom lies on a twofold rotation axis and has a distorted octa-hedral coordination geometry defined by four O atoms from four 4-methyl-benzoate ligands and two N atoms from one 2,2'-bipyridyl ligand. The crystal structure is stabilized by inter-molecular hydrogen bonds and π-π stacking inter-actions [the centroid-centroid distance between the parallel pyridyl ring of a 2,2'-bipyridyl and benzene ring of a 4-methylbenzoic group of a neighboring complex is 3.839 (2) Å].

The asymmetric unit of the title complex, [Mn(2)(C(8)H(7)O(2))(4)(C(10)H(14)N(2)O)(2)(H(2)O)](n), contains two crystallographically independent units. In each one, the Mn(II) ions are bridged by two 4-methyl-benzoate (PMB) ligands and one water mol-ecule. In the crystal structure, each Mn(II) ion is coordinated by three PMB ligands, one water mol-ecule and two symmetry-related N,N-diethyl-nicot...

In title compound, [Cu(C(8)H(7)O(2))(2)(C(6)H(6)N(4))(2)], the Cu(II) atom (site symmetry ) is coordinated by two N,N'-bidentate 2,2'-biimidazole ligands and two weakly bonded 4-methyl-benzoate anions, resulting in a strongly elongated trans-CuO(2)N(4) octa-hedral geometry. In the crystal, adjacent mol-ecules are linked via pairs of N-H⋯O hydrogen bonds into chains propagating in [010].

In the dimeric title compound, [Zn(2)(C(14)H(9)O(4))(4)(C(10)H(8)N(2))(2)], the Zn(II) ions are penta-coordinated by one 2,2'-bipyridyl ligand and by three O atoms from three 2'-carboxyl-atobiphenyl-2-carboxylic acid ligands. Two of the 2'-carboxyl-atobiphenyl-2-carboxylic acid ligands act as bridging ligands and, together with two zinc(II) cations, produce an 18-membered ring system. The remai...
