Some platinum(II) complexes derived from aromatic alkynes

Abstract

Abstract Several trans ‐platinum(II) complexes, of the type R′{Pt(PBu 3 ) 2 }R″{Pt(PR 3 ) 2 }R′, where R′ and R″ are groups derived from a series of aromatic alkynes and diynes, have been prepared and characterized. Extensive spectroscopic data for these and other known related complexes are presented. A more precise structural study of trans ‐Pt(C≡CC 6 H 4 C≡CPh) 2 (PBu 3 ) 2 (cf. Z. Kristallogr . 1998; 213: 483) is reported. Copyright © 2002 John Wiley & Sons, Ltd.
