Synthesis and Crystal Structure of a Chain Complex of Molybdenum(II) Acetate and 1,2-Bis(4-pyridyl)ethane Aiming at N2-Adsorption Property

摘要

The title compound, a chain adduct of molybdenum(II) acetate with 1,2-bis(4-pyridyl)ethane (bpe), catena(tetrakis(μ-acetato-O,O′)(μ-1,2-bis(4-pyridyl)ethane-N,N′)dimolybdenum(II)), [Mo₂(CH₃CO₂)₄(bpe)]_n, was synthesized, and 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 = 7.8313(12)Å, b = 8.5393(13)Å, c = 9.9498(14)Å, α = 73.412(3)°, β = 68.894(2)°, γ = 73.198(3)°, V = 581.86(15)Å3, D_x = 1.747 g/cm3, and Z = 1. The R1 [I 2σ(I)] and wR2 (all data) values are 0.0309 and 0.0680, respectively, for all 2580 independent reflections. The molecule has a zigzag chain structure with an alternating arrangement of Mo₂(CH₃CO₂)₄ [Mo-Mo 2.0984(5)Å] and bpe. The adsorption isotherm was investigated, and no adsorption property was found for N₂.
