Abstract
The crystal structure of a copper(II) complex with 2-pyridinecarboxylic acid anhydride ([Cu2(2-Py)2(H2O)(OH)2(SO4)]) was determined by single-crystal X-ray diffractometry. [Cu2(2-Py)2(H2O)(OH)2(SO4)] crystallized in the orthorhombic system, space group Cmc21, with a = 16.046(2), b = 12.8608(8), c = 12.8905(9)Å, V = 2660.2(4)Å3, Z = 4. The crystal structure was solved by direct methods and refined by full-matrix least squares on F2 to final values of R1 = 0.0613. The complex would produce a π-π interaction between [Cu(2-Py)(OH)2] and [Cu(2-Py)(H2O)(SO4)] in cooperation with a weak coordination of the sulfate ion to the copper(II).
