| Abstract: | The synthesis, X-ray crystallography, spectroscopic, and electrochemical properties of the title compound, Hdpa]Cr(dipic)2]·3H2O, 1, are reported. Compound 1 crystallized in the triclinic space group P-1 with a = 7.1057(11) ?, b = 12.965(2) ?, c = 14.269(2) ?, α = 80.306(3)°, β = 82.101(2)°, γ = 83.799(2)°, and V = 1278.6(4) ?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 π-stacking interactions. |
