Heterotopic ligands offer the possibility of preparing polynuclear bimetallic complexes. Recent studies of heteroditopic ligands and their metal complexes have focused on novel supramolecular systems, biological activity, and the development of MRI contrast agents. The heteroditopic ligand Bipy–CH2–O–CH2–C(pz)3(Bipy-L; Bipy is 2,2′-bipyridine and pz is pyrazolyl) reacts with AgBF4to produce the coordination polymercatena-poly[[silver(I)-(μ-5-{[tris(pyrazol-1-yl)methoxy]methyl-κ2N,N′}-2,2′-bipyridine-κ2N,N′)] diethyl ether hemisolvate], {[Ag(C22H20N8O)]BF4·0.5C4H10O}n, and with Re(CO)5Br to form the discrete compound bromidotricarbonyl(5-{[tris(pyrazol-1-yl)methoxy]methyl}-2,2′-bipyridine-κ2N,N′)rhenium(I), [ReBr(C22H20N8O)(CO)3]. The silver(I) compound is a one-dimensional coordination polymer, built up by a κ2coordination mode of the bipyridine group and a κ2–κ0coordination mode of the –C(pz)3donor set. In [ReBr(Bipy-L)(CO)3], the ligand coordinates onlyviathe bipyridine end, leaving the –C(pz)3donor set free for further coordination interactions.
