| 中文摘要 | We have synthesized a new one-dimensional coordination polymer, [CuII(HL)2(4,4 -bpy)]n·2nH2O (1), (HL– = monodeprotonated 3-nitrophthalic acid, 4,4 -bpy = 4,4 -bipyridine) consisting of infinite chains of [CuII(HL)2(4,4 -bpy)]n and have investigated its structure and magnetic properties. Compound 1 crystallizes in the monoclinic C2/c space group with the [CuII(HL)2(4,4 -bpy)]n chains running parallel to the b axis. The chains are linked together by hydrogen bonding between the HL– groups and water molecules to form the three-dimensional crystal structure. The magnetic suscep-tibility of 1 can be well described using an antiferromagnetic S = 1/2 chain model with g = 2.11(1) and 2J = –0.61(1) cm–1. Several techniques for describing the susceptibility of S = 1/2 chains are examined to compare their validity at low values of kT/|2J|, including exact numerical full-matrix diagonalization techniques, from which the magnetization curve of 1 could be calculated. The calculation fits well with the measured magnetization data. |
