The reaction of [M2Cl2(μ-Cl)2(PR3)2] with NaSeEt in 1:1 and 1:2 stoichiometry gave [M2Cl2(μ-Cl)(μ-SeEt)(PR3)2] and [M2Cl2(μ-SeEt)2(PR3)2] (M=Pd or Pt; PR3=PEt3, PBu3, PMe2Ph or PMePh2), respectively. These complexes were characterized by elemental analysis and NMR data ((1)H and (31)P). The mixed chloro/ethylselenolato bridged complexes adopt a cis configuration with phosphine trans to the bridging chloride. The molecular structure of [Pt2Cl2(μ-SeEt)2(PEt3)2] has been determined by single crystal X-ray diffraction. The complex has a planar four-membered Pt2Se2 bridge.
