Abstract
The novel ionic compound [H2bdtd][CoCl4] · 2H2O (1) was prepared by the reaction between CoCl2 and 2,13-bis(acetamido)-3,14-dimethyl-2,6,13,17-tetraazatricyclo[14,4,01.18,07.12]docosane (bdtd) in adjusted to pH 3.0 by 1.0 M HCl and structurally characterized. The crystals are monoclinic C2/c with a = 18.7777(9), b = 9.7356(4), c = 20.0884(9) Å, β = 109.6340(10)°, V = 3458.9(3) Å3, Z = 4. The dication H2bdtd occupies a special position about an inversion center. The cobalt(II) atom in the anion is in a distorted tetrahedral environment with four chloride ligands. The crystal structure is stabilized by a variety of hydrogen-bonding contacts involving the dication, chloride anions and solvent water molecules. Cyclic voltammetry of [CoCl4]2− anion in 1 undergoes irreversible one-electron reduction to the CoII/CoI.
Graphical abstract
The crystal structure of the ionic compound [H2bdtd][CoCl4] · 2H2O (1) consists of [H2bdtd]2+ cation, [CoCl4]2− anion and water molecules joined together by ionic interaction and hydrogen bonds.
