Strategies for the Construction of Supramolecular Dimers versus Homoleptic 1D Coordination Polymers Starting from the Diphosphorus [Cp 2 Mo 2 (CO) 4 (η 2 ‐P 2 )] Complex and Silver(I) Salts

The reactions of the tetrahedral diphosphorus [Cp 2 Mo 2 (CO) 4 (η 2 ‐P 2 )] ( 1 ; Cp = C 5 H 5 ) complex with Ag[Al{OC(CF 3 ) 3 } 4 ] (AgTEF) ( A ) and Ag[FAl{OC(C 6 F 5 )(C 6 F 10 )} 3 ] (AgFAl) ( B ) were studied. The first reaction led to the formation of the [Ag 2 (η 2 ‐ 1 ) 2 (η 1 :η 1 ‐ 1 ) 2 ][TEF] 2 ( 2 ) dimer and the [Ag 2 (η 1 :η 1 ‐ 1 ) 3 ] n [TEF] 2 n ( 3 ) coordination polymer, whereas the second reaction afforded the [Ag 2 (η 1 :η 1 ‐ 1 ) 2 (η 1 ‐CH 2 Cl 2 ) 2 (η 2 ‐C 7 H 8 ) 2 ][FAl] 2 ( 4 ) or the [Ag 2 (η 2 ‐ 1 ) 2 (η 1 :η 1 ‐ 1 ) 2 ][FAl] 2 ( 5 ) dimer and the [Ag 2 (η 1 :η 1 ‐ 1 ) 4 ] n [FAl] 2 n ( 6 ) coordination polymer. In each case, the products obtained depended on the ratio of the reactants and/or the synthetic procedure.
