[CuCl(C₁₂H₉N₂O₅)(C₁₂H₁₀N₂O₅)(H₂O)]

Abstract

In the title compound, aquachloro(1-ethyl-1,4-dihydro-4-oxo-1,3-dioxolo[4,5-g]cinnoline-3-carboxylato-O 3 ,O 4 )-(1-ethyl-1,4-dihydro-4-oxo-1,3-dioxolo[4,5-g]cinnoline-3-carboxylic acid-O 3 ,O 4 )copper(II) the Cu II ion adopts a tetragonally distorted octahedral geometry. In the equatorial plane, the Cu II ion is coordinated to two O atoms (O keto and O carboxylate ) of one cinoxacinate ligand, and to two O atoms (O keto and O carboxylic ) of one cinoxacin molecule. The apical positions are occupied by one O atom from the water molecule and one Cl - ion, resulting in a CuClO 5 chromophore.
