Synthesis and Properties of Dicyclohexyltin(Ⅳ) Complexes. Structure of Cy2Sn(S2CNMe2)2
Ok-Sang Jung, Min Jung Kim, Jong Hwa Jeong, Youn Soo Sohn*
Dicyclohexyltin(Ⅳ) complexes Cy2SnX (X = O, S, (Me2NCS2)2) have been prepared and characterized by means of elemental analysis, cryoscopic data, and IR spectroscopy. X-ray structure determination for Cy2Sn(S2CNMe2)2 (monoclinic; P2/c;a = 8.992(1), b = 6.688(1), c = 19.453(2) Å, β = 96.556(7) ; R = 0.041) has shown that the molecule is C2-symmetric with both dithiocarbamate ligands bonding in anisobidentate mode and the local geometry around the hexacoordinate Sn(Ⅳ) atom is a distorted octahedral arrangement with the two cyclohexyl groups in trans position. The physical and chemical properties measured suggest polymeric and trimeric structures for Cy2SnO and Cy2SnS, respectively.
