A novel binucleus mixed-ligand[Cd2(phen)4(bmal)2]·3H2O (phen=phenanthroline; bmal=benzylmalonic acid radical) has been synthesized by the reaction of phen and bmal with cadmium(Ⅱ) salt. X-ray crystal structure analysis was carried out to determine the crystal structure of the title complex. The crystal of the title complex belongs to monoclinic system with space group P21/c, a=1.119 1(8) nm, b=2.480 5(17) nm, c=1.063 4(8) nm, β=142.042(12)°, Z=4, V=2.887(3) nm3, Dc=1.613 g·cm-3, R1=0.046 2, wR2=0.115 6, F(000)=1 424. One carboxyl of bmal is coordinated to Cd(1) with monodentate form, the others are coordinated to Cd(2) with bidentate form. The complexes form a 1-D chain structure bridged by hydrogen bonds that formed by uncoordinated water and oxygen atom of carboxyl group in bmal, the 2-D network structure was formed by π-π interaction of neighbouring phen.

Cu(Ⅱ)-牛磺酸缩水杨醛席夫碱配合物的合成及晶体结构   总被引:21,自引:1,他引:21  
The title complex was synthesized by reaction of taurine salicylic schiff base(TSSB), O-phenanthroline(phen) and cupric acetate in water-ethanol solution. The crystal structure was determined by X-ray diffraction method and the chemical formula weight of the complex is 498.00. And the crystal structure belongs to orthorhombic system with space group Pbcn and cell parameters: a=31.072(4)?, b=12.8909(18)?, c=10.3478(14)?; V=4144.7(10)?3,Z=8,Dc=1.596Mg·m-3,μ=1.197mm-1 and F(000)=2048. The compound is an one-dimensional chain complex of infinite length connecting with hydrogen bonds. The Cu(Ⅱ) was coordinated by two oxygen atoms and three nitrogen while the O atoms of Ac- groups did not coordinate. At the same time the Cu(Ⅱ)formed a distorted tragonal cone. Besides the capacities of coordination to Cu(Ⅱ) of atoms were discussed.  相似文献

1 INTRODUCTION Polymeric manganese complexes with fascinating topological chemistry have received considerable interest[1, 2]. The complexation of phen with man- ganese ion gives rise to a wide variety of coordi- nation complexes; however, (phen)Mn coordina- tion polymers are rare since the chelation of phen results in 1 to 3 5-membered chelating rings, ob- structing the way towards the coordination poly- mer. Similar situation has also been observed for 2,2?-bipyridine (bpy) which has si…  相似文献

1 INTRODUCTION Cadmium (Ⅱ) complexes have been exten- sively studied from both chemical and structural views, mainly due to the capability of cadmium (Ⅱ) (shared by most d10 metal ions) to adopt different modes of coordination determined by the consideration of size, as well as electrostatic and covalent bonding forces[1]. And the field of coordination polymers has witnessed tremendous growth over the last decade[2]. Many coordination polymeric networks have been shown to posses intere…  相似文献

A binuclear samarium(III) complex with benzoic acid and 1,10‐phenanthroline, [Sm(BA)3phen]2 was synthesized and characterized by elemental analysis, UV, IR and TG‐DTG techniques. The structure of the title complex was established by single crystal X‐ray diffraction. The crystal is triclinic, space group P1 with a = 10.8216(11) Å, b = 11.9129(13) Å, c = 12.425(2) Å, α = 105.007(2)°, β = 93.652(2)°, γ = 113.2630(10)°, Z = 1, Dc = 1.650 mg·m?3, F(000) = 690. The carboxylate groups are bonded to the samarium ion in three modes: bidentate chelating, bidentate bridging, and tridentate chelating‐bridging. Each Sm3+ ion is coordinated to one bidentate chelating carboxylate group, two bidentate bridging and two tridentate chelating‐bridging carboxylate groups, as well as one 1,10‐phenanthroline molecule, forming a nine‐coordinate metal ion. Based on thermal analysis, the thermal decomposition process of [Sm(BA)3phen]2 has been derived.  相似文献
