[(Cu3(pdp)6Cl2)(H5PMo11CuO39)2]·12H2O (2). In complex 1, the bidentate H2bdpm ligands link CuI centers to form a 1D wave-like metal–organic chain. Adjacent chains are parallel with each other, with Wells–Dawson anions occupying the gaps. In complex 2, six pdp ligands are coordinated to three CuII centers to form a trinuclear cluster. Two Cl− anions are also coordinated to the copper centers. The mono-Cu(II)-substituted
通过使用两种吡唑衍生物,一种对称的,即 1,1'-双(3,5-二甲基-1H-吡唑-4-基)甲烷 (H2bdpm),和一种不对称的,即 4-丙基-4,5 -二氢-1H-吡唑 (pdp),分别由饱和 Wells-Dawson 和单-Cu(II) 取代的 Keggin 阴离子构建的两种基于多金属氧酸盐 (POM) 的配合物,分别通过水热合成和结构表征为 [(Cu2(H2bdpm) )2)[H2P2W18O62]0.5]·2H2O (1) 和 [(Cu3(pdp)6Cl2)(H5PMo11CuO39)2]·12H2O (2)。在配合物 1 中,双齿 H2bdpm 配体连接 CuI 中心以形成一维波状金属有机链。相邻链彼此平行,Wells-Dawson 阴离子占据间隙。在复合物 2 中,六个 pdp 配体与三个 CuII 中心配位形成三核簇。两个 Cl− 阴离子也与铜中心配位。单-Cu(II) 取代的
