Novel Two- and Three-Dimensional Organometallic–Organic Hybrid Materials Based on Polyphosphorus Complexes

The
reaction of the silver salt Ag­[Al­{OC­(CF3)3}4] (1) with the P2 ligand complex [Cp2Mo2(CO)4(η2-P2)] (2) and the organic ditopic linker trans-1,2-di­(pyridine-4-yl)­ethene (dpe) results in the
formation of four novel organometallic–organic hybrid compounds.
Depending on the reaction conditions, the two-dimensional networks
[{Cp2Mo2(CO)4(μ4,η1:1:2:2-P2)}­(μ,η1:1-C12H10N2)­Ag]n[Al­{OC­(CF3)3}4]n·0.075nCH2Cl2·1.425nC6H6 (3) and [{Cp2Mo2(CO)4(μ3,η2:2:2-P2)}2(μ,η1:1-C12H10N2)3Ag2]n[Al­{OC­(CF3)3}4]2n·2nC7H8 (4) are accessible. The latter
shows a two-dimensional (2D) → 2D interpenetration structure.
Furthermore, the formation of a unique three-dimensional polymer [{Cp2Mo2(CO)4(μ4,η1:1:2:2-P2)}­(μ,η1:1-C12H10N2)­Ag]n[Al­{OC­(CF3)3}4]n·0.3nCH2Cl2 (5b) together with another 2D polymer [{Cp2Mo2(CO)4(μ4,η1:1:2:2-P2)}­(μ,η1:1-C12H10N2)3Ag2]n[Al­{OC­(CF3)3}4]2n·0.75CH2Cl2·0.5C7H8 (5a) was observed. In three of
these polymers, unprecedented organometallic nodes were realized including
one, two, or even four silver cations. All products were characterized
by X-ray structural analysis and classified by the structural characteristics
in three different network topologies.
