Abstract

The synthesis, X-ray crystallography, spectroscopic, and electrochemical properties of the title compound, [Hdpa][Cr(dipic)(2)] center dot 3H(2)O, 1, are reported. Compound 1 crystallized in the triclinic space group P-1 with a = 7.1057(11) angstrom, b = 12.965( 2) angstrom, c = 14.269( 2) angstrom, alpha = 80.306( 3)degrees, beta = 82.101(2)degrees, gamma = 83.799(2)degrees, and V = 1278.6(4) angstrom(3) with Z = 2. The distorted octahedral chromium anions are part of an elaborate network of hydrogen bonding formed by the waters of solvation, the anion, and cation as well as pi-stacking interactions.
