Reactions of SmI2 in THF with ArSSAr produced two binuclear samarium thiolate complexes [(THF)3I2- Sm(μ-SAr)]2 [Ar=Ph (1), 4-Me2NC6H4 (2)] in high yields. The structure of 2 was characterized by single crystal X-ray crystallography. The crystal of 2 belongs to the triclinic system with space group P 1 and a=0.95705(13) nm, b= 1.22287(14) nm, c= 1.26450(14) nm, a=64.194(11)°, B=78.491(13)°, y=76.176(12)°, V= 1.2860(3) nm^3, Z= 1,μ=4.783 mm^-1, Dc= 1.964 Mg/m^3, M= 1521.19, S= 1.046, R1=0.0358, wR2=0.0910. X-ray analysis revealed that 2 is a thiolate-bridged dimer in which each Sm atom adopts a distorted pentagonal bipyramidal coordi- nation geometry.  相似文献

1 INTRODUCTION Polyoxomolybdates have been of great interest due to their unique structural varieties, associated multitude of properties and applications as catalysis, medicine and material[1, 2]. One of the most impor- tant aspects is the synthesis and investigation of the materials on polyoxomolybdates containing organo- metallic groups[3~5]. Such materials can provide molecular models for heterogeneous catalysis and display cooperative effects or bifunctional catalytic activity[6]. O…  相似文献

A novel Mn(Ⅱ) complex Mn2(phen)2(p-MBA)4(H2O) has been hydrothermally synthesized by the reaction of p-methyl benzoic acid (p-MBA) with 1,10-phenanthroline (phen). Crystal data for this complex: monoclinic, space group C2/c, a= 2.3328(3), b =1.5549(2), c = 1.5557(2) nm, β = 121.726(2)°, V= 4.7997(11) nm^3, Mr = 1028.85, Dc = 1.424 g/cm^3, Z = 4, F(000) = 2128, μ(MoKa) = 0.590mm^-1, GOOF = 1.060, R = 0.0333 and wR = 0.0767. In the crystal, each Mn(Ⅱ) ion is coordinated by two nitrogen atoms from one o-phenanthroline molecule, three oxygen atoms from three p-methyl benzoic acids and one oxygen atom from one water molecule, giving a six-coordinate distorted octahedral coordination geometry. Two neighboring Mn(Ⅱ) ions are bridged by two p-methyl benzoic acid groups and one water molecule, and their end positions are respectively coordinated by one 1,10-phenanthroline and one p-methyl benzoic acid molecule, giving a binuclear cage structure, of which the Mn(Ⅱ)…Mn(Ⅱ) distance is 0.3502 nm.  相似文献
