Abstract The crystal and molecular structure of the complex [Cu(HBIP) (BIP)ONO2] (HBIP = 3,3-bis(2-imidazolyl)propionic acid) has been determined by X-ray methods. It crystallises in the monoclinic space group C2/c, Z=4, a=11.350(2), b=13.156(2), c=14.225(2) A , s=95.36(2)°, V=2114.8(6) A 3 . The CuN4O chromophore could be considered as an intermediate between the trigonal bipyramid (TBP) and square
摘要用X射线法测定了[Cu(HBIP)(BIP)ONO2](HBIP = 3,3-双(2-咪唑基)丙酸)络合物的晶体和分子结构。它在单斜空间群C2 / c中结晶,Z = 4,a = 11.350(2),b = 13.156(2),c = 14.225(2)A,s = 95.36(2)°,V = 2114.8(6) )A 3。CuN4O发色团可被视为三角双锥(TBP)和四棱锥(SP)之间的中间体。配合物的相邻分子在COO-和COOH基团之间通过短至2.478 A的非常强的氢键结合。电子和EPR光谱与晶体学数据一致。
