Synthesis and Crystal Structure of a Chain Complex of Molybdenum(II) Acetate and trans-1,2-Bis(4-pyridyl)ethylene in Relation to the N2-Adsorption Property

摘要

The title compound, a chain adduct of molybdenum(II) acetate with trans-1,2-bis(4-pyridyl)ethylene (bpel), catena(tetrakis(μ-acetato-O,O′)(μ-trans-1,2-bis(4-pyridyl)ethylene-N,N′)dimolybdenum(II)), [Mo₂(CH₃CO₂)₄(bpel)]_n, was synthesized, and the crystal structure was determined by the single-crystal X-ray diffraction method at 90 K. It crystallizes in the triclinic space group P1 with a = 7.6144(15)Å, b = 8.4800(16)Å, c = 9.7140(19)Å, α = 99.026(3)°, β = 112.749(3)°, γ = 103.210(3)°, V = 541.72(18)Å3, D_x = 1.871 g/cm3, and Z = 1. The R1 [I 2σ(I)] and wR2 (all data) values are 0.0336 and 0.0898, respectively, for all 2324 independent reflections. The molecule has a zigzag chain structure with an alternating arrangement of Mo₂(CH₃CO₂)₄ and bpel [Mo-Mo 2.1038(5)Å, Mo-N 2.591(3)Å]. The adsorption isotherm was investigated and no adsorption property was found for N₂.
