Synthesis and Crystal Structure of a Chain Complex of Molybdenum(II) Benzoate with 1,2-Bis(4-pyridyl)ethylene Having an N2-Adsorption Property

摘要

A chain complex of molybdenum(II) benzoate with 1,2-bis(4-pyridyl)ethylene (bpel), catena(tetrakis(μ-benzoato-O,O′) (μ-1,2-bis(4-pyridyl)ethylene-N,N′)dimolybdenum(II)), [Mo₂(C₆H₅CO₂)₄(bpel)]_n, was synthesized; the crystal structure was determined by the single-crystal X-ray diffraction method at 293 K. It crystallizes in the triclinic space group P1 with a = 8.2328(10)Å, b = 10.5428(13)Å, c = 12.0915(6), α = 114.438(2)°, β = 90.934(2)°, γ = 108.726(2)°, V = 891.26(19)Å3, D_x = 1.600 g/cm3, and Z = 1. The R1 [I 2σ(I)] and wR2 (all data) values are 0.0415 and 0.0864, respectively, for all 3904 independent reflections. The molecule has a chain structure with an alternating arrangement of Mo₂(C₆H₅CO₂)₄ and bpel [Mo-Mo 2.1098(5)Å, Mo-N 2.610(3)Å]. The N₂ adsorption isotherm was investigated, and a Type II adsorption property with a S_BET value of 2.1 m2 g-1 was found.
