The reaction of triethylammonium 2,2,5-triphenyl-1,3,2,5-dioxaborataph
osphorinane with PtCl2(PhCN)(2) gave a complex whose structure was g-i
ven as cis-bis-P,P'-(triethylammonium ,2,5-dioxaborataphosphorinane)di
chloroplatinum(II) on the basis of H-1 and P-31 NMR, medium- and long-
wave IR spectroscopy, and conductometry.
