Abstract
The crystal structure of the title complex has been determined from diffractometer data by three-dimensional Patterson, Fourier, and least-squares methods to R 0.049 for 3 072 independent reflections. Crystals are monoclinic, space group P21/n, with unit-cell dimensions a= 21.230(9), b= 11.493(5), c= 12.091 (5)Å, β= 100.47(4)°, and Z= 4. The co-ordination around the metal is distorted square bipyramidal and involves both the deprotonated and the neutral organic ligands, which are chelated through the carbonyl oxygen [Cu–O(3) 2.062(3), Cu–O(1) 2.334(4)Å], a hydrazide nitrogen [Cu–N(5) 1.930(4), Cu–N(2) 2.043(4)Å], and the pyridine nitrogen [Cu–N(4) 2.081(3), Cu–N(1) 2.277(4)Å]. Packing is determined by a system of O–H ⋯ O hydrogen bonds involving the neutral ligand, the ethanol molecule, and the [ClO4]– group.Keywords
