摘要 The synthesis, structure, and magnetic properties of four 2,2￠-dipyridylamine ligand (abbreviated as Hdpa) containing copper(II) complexes. There is one binuclear compound, which is [Cu2(m1,1-NCO)2(NCO)2(Hdpa)2] (1), and three mononuclear compounds, which are [Cu{N(CN)2}2(Hdpa)2] (2), [Cu(CH3CO2)(Hdpa)2·N(CN)2] (3), and [Cu(NCS)(Acac)] (4). Compounds 1 and 4 crystallize in the monoclinic system, space group P2(1)/c and Z = 4, with a = 8.2465(6) A, b = 9.3059(7) A, c = 16.0817(12) A, b = 91.090(1)°, and V = 1233.90(16) A3 for 1 and a = 7.6766(6) A, b = 21.888(3) A, c = 10.4678(12) A, b = 90.301(2)°, and V = 1758.8(4) A3 for 4. Compounds 2 and 3 crystallize in the triclinic system, space group P-1 and Z = 1, with a = 8.1140(3) A, b = 8.2470(3) A, c = 9.3120(4) A, b = 102.2370(10)°, and V = 592.63(4) A3 for 2 and a = 7.4780(2) A, b = 12.5700(3) A, c = 13.0450(3) A, b = 96.351(2)°, and V = 1211.17(5) A3 for 3. Complex (1), the magnetic data was fitted by the Bleaney-Bowers equation (1). A very good fit was derived with J = 23.96, Q = -1.5 (g = 1.97). Complex (1) shows the ferromagnetism. Complexes (2), (3) and (4) of have the it is the typical paramagnetic behavior of unpaired electrons. Under a low temperature around 25 K, complexes (2) and (3) show weak ferromagnetic behavior. They are the cause of hydrogen bonds.
