Strategies for the Construction of Supramolecular Dimers versus Homoleptic 1D Coordination Polymers Starting from the Diphosphorus [Cp2Mo2(CO)4(η2-P2)] Complex and Silver(I) Salts

Abstract

The reactions of the tetrahedral diphosphorus [Cp2Mo2(CO)4(η2-P2)] (1; Cp = C5H5) complex with Ag[Al{OC(CF3)3}4] (AgTEF) (A) and Ag[FAl{OC(C6F5)(C6F10)}3] (AgFAl) (B) were studied. The first reaction led to the formation of the [Ag2(η2-1)2(η1:η1-1)2][TEF]2 (2) dimer and the [Ag2(η1:η1-1)3]n[TEF]2n (3) coordination polymer, whereas the second reaction afforded the [Ag2(η1:η1-1)2(η1-CH2Cl2)2(η2-C7H8)2][FAl]2 (4) or the [Ag2(η2-1)2(η1:η1-1)2][FAl]2 (5) dimer and the [Ag2(η1:η1-1)4]n[FAl]2n (6) coordination polymer. In each case, the products obtained depended on the ratio of the reactants and/or the synthetic procedure.
