Discrete and Polymeric Organometallic‐Organic Hybrid Materials Based on the Diphosphorus Complex [Cp2Mo2(CO)4(η2‐P2)], CuI Salts, and 2,2′‐Bipyrimidine

Abstract

The reaction of the diphosphorus complex [Cp2Mo2(CO)4(η2‐P2)] (1), with the CuI salts [Cu(CH3CN)4][BF4] or [Cu(CH3CN)4][PF6], and a mixture of [Cu(CH3CN)4][BF4] and CuCl in the presence of 2,2′‐bipyrimidine (2) is studied. Depending on the CuI salts used and the layering solvent involved in the crystallisation, a variety of novel coordination compounds are accessible in moderate to excellent yields (26–80 %): the novel dicationic molecular organometallic‐organic hybrid complexes [{Cp2Mo2(CO)4(µ3,η1:2:2‐P2)}4(µ2,η1:1:1:1‐C8H6N4)Cu2][BF4]2 (3) and [{Cp2Mo2(CO)4(µ3,η1:2:2‐P2)}2{Cp2Mo2(CO)4(µ3,η2:2:2‐P2)}2(µ2,η1:1:1:1‐C8H6N4)Cu2][PF6]2 (4), the unique neutral 1D organometallic‐organic hybrid polymer [{Cp2Mo2(CO)4(µ4,η1:1:2:2‐P2)}2(µ2,η1:1:1:1‐C8N6N4)(CuCl)2]n (5) and the unprecedented 2D organometallic‐organic hybrid polymer [{Cp2Mo2(CO)4(µ4,η1:1:2:2‐P2)}(µ2,η1:1:1:1‐C8H6N4){Cu2(µ‐Cl)}]2[BF4]2n (6).
