The crystal data are as follows: crystal system, orthorhombic; space group, C2221(#20); a=1.18315(3) nm, b=1.28631(5) nm, c=1.14355(2) nm, V=1.74037(9) nm3, Z=4, Dc=1.857 g·cm-3, F(000)=980.00, μ(Mo)=21.69 cm-1, R1=0.030, wR2=0.92. The coordination geometries around Co(Ⅲ) and Mn(Ⅱ) atoms are distorted octahedral and distorted trigonal bipyramidal, respectively. The Hdmg chelates Co(Ⅲ) and bridges to two Mn(Ⅱ) atoms to form a polyheteronuclear helical structure along the c axis.  相似文献

A new binuclear copper(Ⅱ) complex, [Cu2(phen)2(H2O)22-C2O4)](NO3)2, has been synthesized and characterized by elemental analysis, IR and UV-Vis spectrum. Its crystal structure was determined by single crystal X-ray diffraction techniques. Crystal data: monoclinic, space group P21/c, a=0.712 21(8) nm, b=1.170 93(14) nm, c=1.783 7(2) nm, β=111.828(2)°, and V=1.380 8(3) nm3, Dc=1.769 Mg·m-3, Z=2, F(000)=744, R1=0.025 4, wR2=0.069 5, Gof=1.077, Δρ=328~-455 e·nm-3. The complex is packed by one centrosymmetry binuclear copper(Ⅱ) unit, oxalate dianion and NO3- anion. In the molecule structure of the title complex, two Cu(Ⅱ) ions are bridged by oxalate dianion and each Cu(Ⅱ) ions coordinates with two nitrogen atoms from 1,10-phenanthroline ligand and one oxygen atom from water to form a five-coordinate distorted square-pyramidal configuration. The hydrogen bonds are observed between coordinated water molecules and NO3- anions. The analysis of the crystal structure indicates that the complex has a two-dimensional stacking network structure, which is formed by intramolecular hydrogen bonds, intermolecular hydrogen bonds and stacking effect of aromatic ring.

Cis-dioxo-tungsten(Ⅵ) complex, (NH2CH2CH2NH2)[(NH2CH2CH2NH3)2WO2(NHC6H4NH)2]2·H2O is synthesized at room temperature by the reaction of sodium tungstate with o-phenylenediamine. The crystal structure of complex was determined by X-ray diffraction structural analysis. The results show that complex belongs to monoclinic system with space group P21/ c, a=0.712 8(2) nm, b=3.081 1(10) nm, c=0.981 9(3) nm, β=102.615(4)°, V=2.104 4(11) nm3, Z=2, μ=55.26 cm-1, F(000)=1 176. Compared the complex with its analogous biomimetic complexes of the cofactor of molybdoenzymes and tungstoenzymses, it is found that the variance of the coordination atoms and the metal ions center have no influence on the coordination feature, and exhibits distored octahedral coordination with cis-dioxo o-phenylenediamine.

The complex crystallizes in the monoclinic space group P21 with a=1.161 1(4) nm, b=0.717 2(2) nm, c=2.074 1(7) nm, β=101.028(6)°, V=1.695 4(9) nm3, Dc=1.760 g·cm-3, Z=4, μ=1.493 mm-1, F(000)=916, R=0.052 2, wR=0.127 9 for 7 131 unique reflections. The cations of [Cu2(L-ala)2(phen)2]n2n+ have an one-dimensional polymeric structure, due to the bridging of two Cu(phen)2+ units by a carboxylate group of L-alaninate, and each Cu(Ⅱ) ion is in a slightly distorted square-pyramidal coordination geometry, with the phen (N,N′) and the L-ala(N,O) acting as bidentate ligands in the equatorial plane and another carboxylate oxygen atom from a symmetry-related neighboring L-alaninate ion in the apical position.
