J. Lorberth et al., SYNTHESIS AND STRUCTURE OF DIETHYLTINDICHLORIDE METHYLENEDIPHOSPHINATO COMPLEX - ET2SNCL2-CENTER-DOT[ME((I)PRO)P(O)]2CH2, Journal of organometallic chemistry, 480(1-2), 1994, pp. 163-166
In the title complex the disphosphinato ligand coordinates in a chelat
e mode to give a distorted octahedral environment at tin with the ethy
l groups in a trans position.
