A μ-ethoxido-bridged tetranuclear oxidovanadium(IV) complex with 2,6-bis(hydroxymethyl)-4-methylphenol (H3bhmp), (Et3NH)2[(VO)4(Hbhmp)2(EtO)2(SO4)2]·H2O (1) was synthesized. The crystal structure was determined by the single-crystal X-ray diffraction method at 90 K. Compound 1 crystallizes in the trigonal space group R3 with a = 45.690(8)Å, c = 12.589(2)Å, V = 22758(9)Å3, Dx = 1.451 g/cm3, and Z = 18. The R1 [I > 2σ(I)] and wR2 (all data) values are 0.0614 and 0.1701, respectively. Compound 1 consists of triethylammonium cations and the di-μ-sulfato-di-μ-ethoxido-di-μ-alkoxido-di-μ-phenoxido-bridged tetranuclear oxidovanadium(IV) complex anion [(VO)4(Hbhmp)2(EtO)2(SO4)2]2− with a parallelogram array of four vanadium atoms, and water molecules. The adsorption property was studied for N2 gas with a specific surface area of 1.37 m2 g−1, estimated from an N2 adsorption isotherm.
