Abstract:
The crystal and molecular structure of a pyridine complex of anhydrous copper(II)nitrate is described. The structure has been solved by vector search methods and refined by least-squares methods to R(1) = 0.049 [I > 1 > 2 sigma(I)]. The complex lies on a twofold axis parallel to a, and two solvent pyridine molecules lie on twofold axes parallel to c. The copper atom is coordinated by four pyridyl groups and two monodentate NO3 groups. Crystal data: C30H30N8O6Cu, orthorhombic, space group Pnna(52), a = 14.446(7), b = 12.154(5), c = 16.881(4) Angstrom, V = 2964(2) Angstrom(3), Z = 4.
