Abstract :Copper(II) 3,4,5-trimethoxybenzoate, [Cu 2 (3,4,5-(CH 3 O) 3 C 6 H 2 CO 2 ) 4 (CH 3 OH) 2 ]·2DMF, was prepared and characterized by elemental analysis, infrared and UV-vis spectra and temperature dependence of magnetic susceptibilities (4.5—300 K). The crystal structure was determined by the single-crystal X-ray diffraction method. It crystallizes in the triclinic space group P 1 ( _ ) with a = 8.2110(13) Å, b = 13.181(2) Å, c = 13.409(2) Å, α = 97.967(3)°, β = 102.378(3)°, γ = 105.009(3)°, V = 1339.8(4) Å 3 , D x = 1.465 g/cm 3 , and Z = 1. The R 1 [ I > 2σ( I )] and wR 2 (all data) values are 0.0363 and 0.0816, respectively, for all 5991 independent reflections. The crystal contains crystallographically centrosymmetric dinuclear molecule with axial methanol molecules and crystal DMF molecules [Cu···Cu 2.6190(6) Å]. Magnetic susceptibility data show a considerable antiferromagnetic interaction between the two copper(II) ions (2 J = –292 cm –1 ). Gas-adsorption behavior was investigated for N 2 .Keywords : Dinuclear copper complex, crystal structure determinations, nitrogen gas absorption property
