摘要：
X-ray diffraction analysis of the copper(II) chelate complex CuL2 (where L is the deprotonated imid-ol form of N,N-dimethyl-2,4-dichlorophenoxyacetohydrazide (HL)) was performed (3826 reflections, R = 0.039, wR = 0.043). Crystals are monoclinic, a = 8.365(7) Å, b = 23.090(7)Å, c = 12.713(3) Å, β = 95.12(6)°, space group P21/c, Z = 4. The slightly distorted square environment of the copper cation is composed of two N atoms of the dimethylamino groups and two O atoms of the deprotonated imidol groups. Both N and O atoms are located in trans-positions relative to each other. Additional coordination of electron-donor atoms is prevented by methyl groups, in which the C atoms are at a distance of 2.837 to 2.918 Å from the central ion.
