Synthesis, Crystal Structure and Magnetic Properties of a Nd(III) Coordination Polymer Constructed by 3-Carboxyphenoxyacetate and 1,10-Phenanthroline

Abstract

Under hydrothermal conditions, NdCl3 center dot 6H(2)O reacts with 3-H(2)CPOA (3-H(2)CPOA=3-carboxyphenoxyacetatic acid) and phen (phen=1,10-phenanthroline), producing a novel coordination polymer [Nd(3-CPOA)(1.5)(phen)](n) (1). Complex 1 crystallizes in monoclinic space group P2(1)/c, with a=0.982 7(8), b=1.140 6(10), c=2.115 8(19) nm, beta=90.574(9)degrees, V=2.371(4) nm(3), and Z=4. X-ray diffraction studies show that complex 1 possesses a three-dimensional framework structure based on a binuclear unit. Magnetic studies for complex 1 indicate the presence of stronger antiferromagnetic coupling between the adjacent NO ions. CCDC: 888765.
