文摘

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) Å, β = 95.36(2)°, V = 2114.8(6) ų. The CuN₄O chromophore could be considered as an intermediate between the trigonal bipyramid (TBP) and square pyramid (SP). Neighbouring molecules of the complex are bound by very strong hydrogen bonds, as short as 2.478 Å, between COO⁻ and COOH groups. Electronic and EPR spectra are consistent with the crystallographic data.
