✦ Synopsis

The biphosphinine complexes [RuCl,(dmso),(bp)] (2) and cis-[Reclad] (3) (bp = 4,4',5,5'-tetramethyl-2,2'biphosphinine) have been prepared from [RuCl,(dmso),,] and the free ligand. The crystal and molecular structure of 2, which crystallised in the space group C2/c with a = 17.329(l), b = 16.008(l), c = l&733(2) A, p= 104.75(l)", V=5025.2(1.4) A3 and Z = 8 and refined to R = 0.042, R, = 0.089, is presented and NMR data pertaining to both complexes is discussed. Analyses of the complexes suggest that the biphosphinine serves as a good r-acceptor ligand towards the ruthenium(I1) centres. P' (1) dmG0 2 [RuC12(dmso)&Ol + 1 cH~ renux, 9. min ' 0020-1693l92B5.00
