Abstrakt: The pyridyl functionalized amidinate [{PyC≡CC(NDipp) 2 }Li(thf) 2 ] n was used to synthesize a series of bis-amidinate complexes [{PyC≡CC(NDipp) 2 } 2 M 2 ] (M=Cu, Ag, Au) with fully supported metallophilic interactions. These metalloligands were then used as building blocks for the synthesis of one-dimensional heterobimetallic coordination polymers using Zn(hfac) 2 (hfac=hexaflouroacetylacetonate) for self-assembly. Interestingly, the three coordination polymers [{PyC≡CC(NDipp) 2 } 2 M 2 ][Zn(hfac) 2 ] (M=Cu, Ag, Au), exhibit a zig zag shape in the solid state. To achieve linear coordination geometry other connectors such as M'(acac) (M'=Ni, Co) (acac=acetylacetonate) were investigated. The thus obtained compounds [{PyC≡CC(NDipp) 2 } 2 Cu 2 ][M'(acac) 2 ] (M'=Ni, Co) are indeed linear heterobimetallic coordination polymers featuring a metalloligand backbone with fully supported metallophilic interactions.
