Treatment of (CO)AuCl, CuCl or AgNO3 with 2-LiC(SiMe3)2-Py-6-CH2R gives the binuclear metal compounds [M2(μ-2-C(SiMe3)2-6-CH2RPy)2] [R = H, M = Au (1), Cu (2) and Ag (3); R = Me3Si, M = Cu (4)]. The dimeric structures of complexes 1, 2 and 4 have been established by single-crystal X-ray diffraction studies. The complexes are centrosymmetric with each ligand bridging the two metal centres which are in close proximity to each other [M⠯M 2.690(2) ⠫ in 1, 2.436(1) ⠫ in 2 and 2.431(1) ⠫ in 4].
