摘要：
A dimeric chromium compound has been synthesized by hydrothermal method and characterized by IR, EPR spectra and TG-DTA technique. The title compound [Cr(aea)]2(OH)2 (aea = N-(2-aminoethyl)aspartate) crystallizes in monoclinic, space group P21/c with a = 8.9393(10), b = 6.7198(7), c = 14.6791(16), β = 91.0580(10)°, V = 881.63(17) 3, Z = 2, Mr = 486.34, Dc = 1.832 g/cm3, F(000) = 500, μ = 1.296 mm?1, R = 0.0271 and wR = 0.0756. Single-crystal X-ray structural analysis indicates that the title compound consists of two Cr(aea) units linked by two bridging hydroxyl groups. The geometry around each chromium center is approximately octahedral and completed by two hydroxyls and a quadridentate ligand which is formed when ethylenediamine reacts with maleic acid.
