G. Beurskens et al., CRYSTAL AND MOLECULAR-STRUCTURE OF TETRAPYRIDYL-COPPER(II)BIS-NITRATO-BIS-PYRIDINE, Journal of chemical crystallography, 25(7), 1995, pp. 425-427
The crystal and molecular structure of a pyridine complex of anhydrous
copper(II)nitrate is described. The structure has been solved by vect
or 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 monod
entate NO3 groups. Crystal data: C30H30N8O6Cu, orthorhombic, space gro
up Pnna(52), a = 14.446(7), b = 12.154(5), c = 16.881(4) Angstrom, V =
2964(2) Angstrom(3), Z = 4.
