Preparation and structural characterization of [RuCl2(CO)2{Te(CH2SiMe3)2}2] and [RuCl2(CO){Te(CH2SiMe3)2}3]

The reaction of Te(CH2SiMe3)2 and [RuCl2(CO)3]2 affords a mixture of mononuclear ruthenium complexes [RuCl2(CO)2{Te(CH2SiMe3)2}2] (1) and [RuCl2(CO){Te(CH2SiMe3)2}3] (2). The X-ray structures show the formation of the cis(Cl), cis(C), trans(Te) isomer of 1 and the cis(Cl), mer(Te) isomer of 2.
