Crystal structure of the triphenyltin(IV) chloride dimethyl N-cyanodithioiminocarbonate adduct
Abstract
Reaction of dimethyl N-cyanodithioiminocarbonate, NCNC(SCH3)2 (L), and SnPh3Cl led to the formation of [ClPh3SnNCNC(SCH3)2] (1) which crystallizes in the monoclinic space group C2/c with Z=8, a=19.152(2) Å, b=12.8659 (16) Å, c=19.063(3) Å, β=108.608(3) and V=4451.6(10) Å3. The structure of 1 consists of a SnPh3 moiety trans-coordinated in apical positions by one L ligand, N-coordinated, and one chlorine atom involving a trigonal bipyramid geometry around the Sn(IV) atom. To our knowledge, this is the first isolation of a discrete triorganotin(IV) complex with a N-cyanodithioiminocarbonate adduct. The structural characterization of 1 was completed by infrared and nuclear magnetic resonance spectroscopy, and elemental analysis which confirm the X-ray elucidation.
