含有弱Cu—N键的磷钼酸有机衍生物的合成和表征

Synthesis and Characteristics of an Organic Derivative of Phosphomolybdic Acid with Weak Cu-N Bond

具有特种功能杂多酸的研究和应用受到重视.N,N,N′,N′-四[(2-苯并咪唑)甲基]-1,2-乙二胺(简称 EDTB)具有对称结构.在测定六配位的[(EDTB)Cu](NO_3)_2的晶体结构时发现,配位多面体呈现较大的变形,Cu-N 键长在0.1981～0.2437 nm 范围内变化,其中两个乙二胺的氮原子形成的 Cu-N(1)和 Cu-N(2)键长分别为0.2215(5)nm、0.2437(4)nm,

The reaction of E(EDTB)Cu](CH_3COO)_2 with H_3PMo_(12)O_(40)in absolute ethanol produces[(EDTB)Cu](HPMo_(12)O_(40))(C_2H_5OH)_6,in which EDTB is N,N,N′,N′-tetrakis [(2-benzimidazolyl)methyl]-1,2-ethanediamine.A comparative study of IR spectra、UV-Vis spectra,~1H NMR and elemental analysis for the product and reference molecule[(EDTB) Cu](NO_3)_2 confirms the structure of the title compound.
