Synthesis and structure of a novel dimeric dysprosium complex of 3-amino-4-methylbenzoic acid

Abstract

A novel europium coordination complex [Eu(AMBA)3(H2O)2·H2O]2 has been obtained from ethanol solution and characterized structurally by X-ray diffraction (AMBAH=3-amino-4-methylbenzoic acid). The results reveal that it forms a dimeric molecular structure through bridging oxygen atoms of carboxylate groups. The title complex crystallizes in the triclinic system, space group P , with lattice parameters a = 9.084(2), b = 12.331(3), c = 12.357(3) Å, α = 87.055(4), β = 69.657(3), γ = 81.866(3)°, V = 1284.8(6) Å3, D c = 1.697 Mg m−3, Z = 1, F(000) = 660, GOF = 1.050, R 1 = 0.0363.
