摘要：
One novel complex [Co(p-MBA)2(2,2′-bipy)(H 2O)](H20) has been synthesized by the reaction of p-methylbenzoic acid with 2,2′-bipyridine in the solvent mixture of water and methanol. It crystallizes in triclinic, space group P1̄ with a = 0.70479(14), b = 1.1211(2), c = 1.6718(3) nm, α = 103.806(3), β= 90.795(3), γ = 104.207(3)°, V= 1.2399(4) nm3, Mr = 512.41, Dc= 1.373 g/cm3, Z = 2, F(000) = 532, μ = 0.733 mm-1, R= 0.0432 and wR = 0.0957. The crystal structural analysis shows that the cobalt atom is coordinated with three oxygen atoms from two p-methylbenzoic acids and one water molecule and two nitrogen atoms from one 2,2′-bipyridine, forming a distorted square-pyramidal coordination geometry. The cyclic voltammetry behavior of the complex is also reported.

A novel complex tri(o-bromobenzyl)tin ferrocenecarboxylate has been synthesized and its crystal structure was determined by X-ray diffraction. It belongs to orthorhombic, space group Pbca with a = 1.1340(3), b = 1.7823 (4), c = 3.0119(8) nm, V = 6.088(3) nm~3, M_r = 857.81, Z = 8, D_c = 1.872 g/cm~3, μ(MoKα) = 52.63 cm~(-1), F(000) = 3328, R = 0.0683 and wR = 0.1057. The tin atom adopts a distorted tetrahedral coordination geometry. Further studies on the title com- plex have been performed with quantum chemistry calculation at the Lanl2dz basis set level using G98W package. The stability of the complex, some frontier molecular orbital energies and com- position characteristics of some frontier molecular orbitals have been investigated.

A new manganese coordination polymer 1, [Mn(H_2O)_4(L)]_n(ClO_4)_(2n).2nH_2O.3nL (L= 2,5-bis(4-pyridyl)-3,4-diaza-2,4-hexadiene), has been synthesized and structurally characterized.The crystal structure was determined by single-crystal X-ray diffraction. The crystal is of monoclinic, space group Pn with a = 13.9176(8), b = 15.4754(9), c = 15.9670(9) (A), β =99.5010(10)°, V = 3391.8(3) (A)~3, Z = 2, C_(56)H_(68)Cl_2MnN_(16)O_(14), M_r= 1315.10, D_c = 1.288 g/cm~3, μ =0.344 mm~(-1), F(000) = 1374, R = 0.0733 and wR = 0.2035. In the crystal the manganese atom is six-coordinated by two nitrogen atoms from 2,5-bis(4-pyridyl)-3,4-diaza-2,4-hexadiene and four oxygen atoms from water molecules, completing an octahedral geometry. The title complex exhibits a novel supramolecular layer architecture sustained by the concurrence of coordination bonds,hydrogen bonds, and π-π stacking interactions.

摘要：
A new nickel(II) coordination complex [Ni(phen)3]·(m- nitrobenzoic acid)2-(H2O) was synthesized by self-assembly of m-nitrobenzoic acid, 1,10-phenanthroline and nickelous Perchlorate. It crystallizes in the monoclinic system, space group C2/c, with a = 2.4596(6), b = 1.2124(3), c = 1.9824(5) nm, β = 97.088(5)°, V = 5.866(3) nm 3, Dc = 1.474 g/cm3, Z = 4, Mr = 1301.82, μ(MoKα) = 0.417 mm-1 F(000) = 2688, R - 0.0493 and wR = 0.1025. Structural determination indicates that the nickel(II) ion is coordinated with six nitrogen atoms from three phens, giving a distorted octahedral coordination geometry. The cyclic voltametric analysis shows that the electron transfer in the electrode reaction is irreversible.
摘要：
The title compound, [Mn(2,4,6-TMBA)2(H2O) 3]n·2nH2O (1), where 2,4,6-TMBA=2,4,6-trimethylbenzoic acid, was synthesized and its crystal structure was determined by X-ray diffraction analysis. The crystal is of monoclinic, space group C2/c with a=2.9299(6) nm, 6=1.0364(2) nm, c=8.22204(17) nm, V=2.4947(9) nm3, Z=4, M=471.40, Dc=1.255 g·cm-3, μ=0.571 mm-1, F(000)=996, R int=0.0294, R=0.0376 and wR=0.0949. The Mn atoms are octahedrally coordinated by two O atoms of two ligands and four O atoms of water. The carboxyl group coordinates to Mn(II) in the mode of monodentate, while the O atoms of water molecules coordinates in bridging mode. The complex shows a one-dimensional chain structure bridged by water molecules.

摘要：
The title compound, [Cd(C8H6BrNO4S)(C12H8N2)(CH4O)], incorporating a Schiff base formed by aminomethanesulfonic acid and 5-bromosalicylaldehyde, was synthesized in a water methanol solution. In the structure, the Cd-II atom is six-coordinated by one O atom from a methanol molecule, two N atoms from a 1,10-phenanthroline ligand, and one N and two O atoms from the Schiff base in a distorted octahedral coordination geometry. A one-dimensional chain structure is formed via C-H center dot center dot center dot O hydrogen bonds.
