Synthesis and Crystal Structure of a Novel Heptanuclear Ruthenium- and Sodium-containing Polyoxomolybdate {Na(H2O)3}2{Ru(dmso)3}2(MoO4)3·3H2O
cqvip:The title compound, [{Na(H2O)3}2{Ru(dmso)3}2(MoO4)3]3H2O, has been ob- tained by the reaction of Na2MoO42H2O with cis-Ru(dmso)4Cl2 in aqueous solution. Its crystal structure was determined by single-crystal X-ray diffraction method. The crystal crystallizes in the triclinic system, space group P1 with a = 12.3333(3), b = 12.6289(3), c = 32.0284(14) , α = 79.873(7), β = 87.549(9), γ = 64.500(4)o, V = 4429.5(2) 3, Z = 4, Mr = 1358.85, Dc = 2.038 g/cm3, F(000) = 2696 and μ = 1.874 mm-1. The compound contains a novel pentanuclear triangle bipyramidal core, [{Ru(dmso)3}2(MoO4)3]2-, which consists of two {Ru(dmso)3}2+ fragments and three {μ2-MoO4}2- units. Furthermore, the dmso ligands bridge the pentanuclear [Ru2Mo3] core and two [Na(H2O)3]+ fragments together, forming a neutral heptanuclear ruthenium- and sodium- containing polyoxomolybdate.
