Summary Heterobimetallic complexes of the types [Cp2Ti(μ-EAr)2-M(dppe)] (ClO4)2 [(1)–(4); M, E = Ni, Te (1); Ni, Se (2); Pt, Te (3); Pt, Se (4); Ar = Ph (a), C6H4-4-Me (b), C6H4-4-OMe (c), C6H4-4-OEt (d)] and [Cp2Ti(μ-TeAr)2-MCl 2] [M = Pd (5), Pt (6)] were obtained by the reactions of Cp2Ti(EAr)2 with M(dppe)(ClO4)2 and M(PhCN)2Cl2, respectively. While (1), (5) and (6) are stable in the solid state as well as in solution, (2)–(4) undergo dissociation to M(dppe)(EAr)2 and Cp2Ti(ClO4)2 in solution, as shown by multinuclear (31P{1H},195Pt{1H}, 125Te{1H}) n.m.r. studies. The reaction of Cp2Ti(SeAr)2 with M(PhCN)2Cl2, however, leads to the formation of Cp2TiCl2 and a polymeric material [M(SeAr)2] n .
