Abstract
The title compound, a chain adduct of molybdenum(II) benzoate with 1,2-bis(4-pyridyl)ethane (bpe), catena(tetrakis(μ-benzoato-O,O′)(μ-1,2-bis(4-pyridyl)ethane-N,N′)dimolybdenum(II)), [Mo2(C6H5CO2)4(bpe)]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 = 8.2457(17)Å, b = 10.506(2)Å, c = 12.142(3)Å, α = 114.583(4)°, β = 90.398(4)°, γ = 108.768(4)°, V = 893.4(3)Å3, Dx = 1.599 g/cm3, Dm = 1.60 g/cm3, and Z = 1. The R1 [I > 2σ(I)] and wR2 (all data) values are 0.0362 and 0.0716, respectively, for all 3971 independent reflections. The molecule has a chain structure with an alternating arrangement of Mo2(C6H5CO2)4 and bpe [Mo-Mo 2.1095(5)Å, Mo-N 2.608(2)Å]. The N2 adsorption isotherm was investigated and a Type II adsorption property with a SBET value of 2.47 m2 g-1 was found.
