Novel trinuclear disilver(I)-copper(II) complexes, [Ag(PPh3)(2)](2)[Cu(mtm)(2)] (1) and [Ag-2(dppm)(2)][Cu(mtm)(2)] (2) (mtm = [bis(methylthio)methylene]malonate, dppm = bis(diphenylphosphino)methane) have been prepared and characterized by a single-crystal X-ray structure analysis. In the complex 1, a silver atom is coordinated to each of the two carboxylate oxygens with different bond distances of 2.325(5) Angstrom (Ag-O(1)) and 2.653(6) Angstrom (Ag-O(2)). In the case of the complex 2. two silver atoms are bridged by two dppm ligands separated by 3.0130(9) Angstrom and Ag(1) has bonded to O(5) (2.442(5) Angstrom). Interestingly, Ag(2) has bonded to O(4) (2.325(5) A) which is not a coordinated carboxylate oxygen bonded to copper(II) atom. Interaction between silver(I)-thioether group was not observed in I and 2. 0 2002 Published by Elsevier Science Ltd.
