    Abstract: 中文摘要 本論文選擇 1,2,4,5苯四酸為有機配子,取其在鍵結上的豐富的特性設計了一些實驗,和鈷、鋅金屬離子,成功的合成出兩種新的化合物 1、化合物 2 及一個文獻曾被發表的結構化合物 3,化合物 3 在磁性上呈現些許特別的現象。 化合物K2Zn(C10H2O8)·8H20 (1),屬於單斜晶系,空間群為 C 2/c 1 (15),a = 11.3366(10) Å,b = 15.3829(10) Å,c = 11.1085(10) Å,β= 91.40(1)°,V = 1936.63(55) Å3。 化合物K2Co3(H2O)4(C10H2O8)2·6H2O (2),屬於單斜晶系,空間群 C 2/m (12),a = 15.5442(10) Å,b = 11.8815(10) Å,c = 9.4204(10) Å,β = 113.08(1)°,V = 1600.56(683) Å3。 化合物Co5(OH)2[(C10H2O8)2(H2O)4] ·5 H2O (3) 屬於單斜晶系,空間群 P 21/n,a = 7.452(4) Å,b = 16.472(6) Å,c = 14.586(5) Å,β= 95.46(4)°,V = 1782.3(13) Å3。 Abstract The preparaction, characteriyal and properties of metal-organic hybrid materials have been selected as the ligand to react with zinc or cobalt metal ions. Self-assembly of compound Zn(C10H2O8)·8H20 (1), compound K2Co3(H2O)4(C10H2O8)2·6H2O (2), and compound Co5(OH)2 [(C10H2O8)2(H2O)4] ·5 H2O (3) has been achieved at room temperature or under hydrothermal conditions. Their structure have been characterized by X-ray diffraction analyses. Single-crystal and powder, Thermal stability and magnetic properity have also been examined. Compound Zn(C10H2O8)·8H20 (1), monoclinic, space group = C 2/c (15), a = 11.3366(10) Å, b = 15.3829(10) Å, c = 11.1085(10) Å , β = 91.40(1)°, V = 1936.63(55) Å3. Compound K2Co3(H2O)4(C10H2O8)2·6H2O (2), monoclinic, space group = C 2/c (15), a = 15.5442(10) Å, b = 11.8815(10) Å, c = 9.4204(10) Å, β = 113.08(1)° V = 1600.56(683) Å3. Compound Co5(OH)2[(C10H2O8)2(H2O)4] ·5 H2O (3), monoclinic, space group P 21/n,a = 7.452(4) Å,b = 16.472(6) Å,c = 14.586(5) Å,β= 95.46(4)°,V = 1782.3(13) Å3。
