Treatment of 2> with 5 equivalents of PhCH2SCH2PPh2 (btmp) gave a mononuclear Vaska-type complex trans-, whereas the reaction with 2 equivalents of btmp afforded not the expected face-to-face complex but the chloro-bridged complex .The tetraphenylborate salt analogue BPh4 was obtained from the reaction of an ethanolic solution of - with 1 equivalent of btmp and NaBPh4.Treatment of n4> with 1 equivalent of btmp afforded the carbonyl-bridged dinuclear complex , while the above reaction performed in the presence of hydrochloric acid gave the novel dinuclear rhodium(II) complex (5).Complex (5) was also obtained from the reaction of an ethanolic solution of - and 1 equivalent of btmp.Crystals of (5) are monoclinic, space group C2/c, with a=14.064(3), b=19.364(4), c=16.930(5) Angstroem, β=116.67(2) deg, and Z=4; final R=0.036 for 3529 observed reflections.The structure shows that there is a metal-metal bond and the two μ-btmp ligands are co-ordinated to rhodium atoms cis to each other with a head-to-tail arrangement.The relationships among the synthesized complexes are discussed.
