REACTIONS OF TIN TETRACHLORIDE WITH DIETHYL GLUTARATE - CRYSTAL-STRUCTURES OF CL8(MU-C3H6(CO(2)ET)(2))(2)]CENTER-DOT-2CH(2)CL(2) AND CIS-[SNCL4(H2O)(2)]CENTER-DOT-C3H6(CO(2)ET)(2)

The dimeric compound [Sn2Cl8{mu-C3H6(CO(2)Et)(2)}(2)]. 2CH(2)Cl(2) 1 h as been prepared by direct reaction of SnCl4 with diethyl glutarate in CH2Cl2 and its crystal structure has been determined. Each tin atom i s octahedrally co-ordinated by four chlorine atoms and two mutually ci s carbonyl oxygen atoms of two bridging diethyl glutarate molecules. D uring the crystallization of 1 the compound cis-[SnCl4(H2O)(2)]. C3H6( CO(2)Et)(2) 2 was formed under the influence of moisture. Its crystal structure revealed a monomeric complex of Sn-IV in which each tin atom is surrounded octahedrally by four chlorine atoms and two water oxyge n atoms. A non-co-ordinated ester molecule is hydrogen bonded through carbonyl oxygen atoms to one water molecule.
