【摘要】 A new five-heterocyclic-biphosphine-substituted Fe-only hydrogenase mimic,[(μ-pdt)Fe2(CO)5]2(PTP)(1),has been synthesized at room temperature. 1·H2O crystallizes in triclinic system,space group P1,with a = 11.5897(4),b = 13.6156(4),c = 18.0333(6) ?,α = 76.306(3),β = 72.742(3),γ = 68.939(3)°,V = 2508.84(14) ?3,Dc = 1.570 g/cm3,Z = 2,Mr = 1186.37,F(000) = 1204,the final R = 0.0748,and wR = 0.2012. In the tetranuclear complex 1·H2O,each [2Fe2S] butterfly unit is attached to one P atom of the diphosphine bridge and exhibits a square-pyramidal geometry. Complex 1 was characterized by elemental analysis,IR spectra,UV-vis absorption spectra,1H-NMR and 31P-NMR. The cyclic voltammetry behavior of compound 1 was investigated as well.
