Synthesis and crystal structure of a chain complex of copper(II) pivalate and 1,2-bis(4-pyridyl)ethane in relation to adsorption property for N2

Abstract

The title compound, a chain complex of copper(II) pivalate with 1,2-bis(4-pyridyl)ethane (bpe), catena(tetrakis(μ- prvalato-0,0')(μ-1,2-bis(4-pyridyl)ethane-N,N')dicopper(n)) [Cu2(piv)4(bpe)]n, was isolated. The crystal structure was determined by the single-crystal X-ray diffraction method at 293 K. It crystallizes in the monoclinic space group C2/c with a = 21.267(3)Å, b = 18.250(2)Å, c = 10.1715(13)Å, p = 99.716(3)°, V = 3891.2(9)Å3, Dx = 1.222 g/cm3, and Z = 4. The R1 [I > 2σ(I)] and wR2 (all data) values are 0.0509 and 0.1360, respectively, for all 4516 independent reflections. The crystal contains zigzag chain molecules with an alternating arrangement of Cu2(piv)4 [Cu···Cu 2.6207(8)Å] and dpe. The adsorption isotherm measurement showed no adsorption property for N2. 2015
