Abstract
Novel trinuclear disilver(I)-copper(II) complexes, [Ag(PPh3)2]2[Cu(mtm)2] (1) and [Ag2(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) Å (Ag-O(1)) and 2.653(6) Å (Ag-O(2)). In the case of the complex 2, two silver atoms are bridged by two dppm ligands separated by 3.0130(9) Å and Ag(1) has bonded to O(5) (2.442(5) Å). Interestingly, Ag(2) has bonded to O(4) (2.325(5) Å) which is not a coordinated carboxylate oxygen bonded to copper(II) atom. Interaction between silver(I)-thioether group was not observed in 1 and 2.
