The thermal behavior consists mainly of the loss of hydrazine moieties leading thus to the formation of anhydrous cobalt phosphate. The phosphate complex exhibits efficiency in catalytic oxidation and degradation of methylene blue dye. The ac magnetic susceptibility
摘要 采用缓慢蒸发法合成了一种新的一维配位聚合物[(N2H5)2Co(HPO4)2],并通过单晶X射线衍射、傅里叶变换红外光谱(FTIR)和热重分析(TGA)表征。 . 其催化活性通过紫外-可见光吸收测量进行了测试。化合物在单斜晶系 (SG: P21 / c) 中结晶,晶胞参数 (A, °): a = 5.3665 (3), b = 11.1271 (6), c = 7.7017 (4), β = 104.843 (4) ), V = 444.55 (4) A3 和 Z = 2. 由线性链组成的晶体结构由 [CoN2O4] 八面体和 [PO3 (OH)] 四面体环组成,这些环通过与钴中心配位的氧原子共享顶点. 这些环与沿 [100] 延伸的链相连,从而形成由氢键以三维排列连接的聚合物链。FTIR 光谱显示了预期的肼和磷酸根基团。热行为主要包括肼部分的损失,从而导致无水磷酸钴的形成。磷酸盐配
