Sw. Ng et al., MU-OXALATOBIS(TRICYCLOHEXYLTIN), A DINUCLEAR TIN COMPOUND WITH ISOMERIC PENTACOORDINATE TIN SITES, Journal of organometallic chemistry, 467(1), 1994, pp. 47-49
An X-ray diffraction study of mu-oxalatobis(tricyclohexyltin) has reve
aled the presence of two symmetry-independent molecules, each of which
contains a pair of tin atoms in an isomeric cis-, trans-C3SnO2 trigon
al bipyramidal configuration arising from the quadridentate (chelating
and bridging) behavior of the oxalato ligand.
