“…The expression for I J(PtP) I given by Pidcock et al [8] shows that smaller coupling constants are associated with Pt-P bonds of lower s-character; the smaller coupling constant corresponds thus to the phosphorus trans to the cyanoalkyl group. Mastin [9] has proposed an assignment of the cis or trans stereochemistry in bis(tripheny1phosphine)platinum(II) complexes based on the relative intensity of an IR. and Raman band at ca.…”

“…In their characteristic features the IR spectra of course are very similar to those of 5 . An additional strong band at 550 cm –1 in the spectrum of 6 suggests cis ‐configuration of the bis(triphenylphosphane)platinum unit 32. At first glance this seems inconsistent with the 31 P‐NMR spectrum showing only one singlet though with two sets of platinum satellites.…”
