Abstract	Abstract Reaction of metal chlorides (MCl2) with tripiperidinophosphine chalcogenides (Pip3PE) produces new dimer species (1–6) of the formula [MCl2(Pip3PE)]2 (Pip = piperidinyl; E = S or Se; M = Hg, Cd or Zn). These coordination complexes were characterized by elemental analysis, IR, multinuclear (31P, 113Cd and 199Hg) NMR spectroscopy and single crystal X-ray analysis. Compounds 1–6 exist as centrosymmetric homobimetallic dimers, [M(µ-Cl)Cl(Pip3PE)]2. Each dimer incorporates two µ2-chloro atoms and two terminal M Cl bonds. The E atom of Pip3PE forms terminal M E bonds {S; 2.305(11); Se: 2.412(6)−2.589(15) A} and thus the geometry about each metal centre is distorted tetrahedral and the range of tetrahedral bond angles is 102.83(3)° to 113.32(3)°. The P Se bond lengths of 2.183(9)–2.205(2) A in the selenide complexes are slightly elongated compared to those in the free ligands [2.1090(4) A]. The results are discussed and compared with those obtained for related analogues.
