Synthesis and crystal structure of one trinuclear di-n-butytin(IV) complex with salicylaldoxime

One trinuclear di-n-butytin(IV) complex with salicylaldoxime (HONZOH=o-HON=CH C6H4-OH), (Bu2Sn)2(Bu2SnO)(OH)(ONZOH)(ONZO), has been synthesized and characterized by elemental analyses, IR spectrum and single crystal X-ray diffraction. This compound is a small cluster displaying two unequivalent salicylaldoximate with one seven-coordinate pentagonal-bipyramidal tin atom linked two five-coordinate trigonal-bipyramidal tin atoms via a network of oxygen atoms by Sn-O-Sn bridges. The hydrogen bonds (o-HON=CHC6H4-O…H-O) are observed in the complex. These hydrogen bonds include intramolecular hydrogen bonds and intermolecular hydrogen bonds. (Bu2Sn)2(Bu2SnO)(OH)(ONZOH)(ONZO) belongs to monoclinic: space group P2(1)/n, with a = 12.2307(15) Å, b = 17.361(2) Å, c = 20.976(3) Å, β = 94.424(2)˚, V = 4440.5(10) Å3, Z = 4, Dc = 1.500g/cm3, μ(MoKα) = 1.715mm-1, F(000) = 2024, and final R1 = 0.0426, wR2= 0.1064 for observed reflections 7779(I > 2ơ(I)).
