Abstract
The asymmetric unit of the title CoIII complex, [Co(NO2)2(C16H32N4)]ClO4·0.5H2O, comprises two complex cations, two perchlorate anions and a water molecule of crystallization. The CoIII atoms exist within distorted octahedral N6 geometries defined by four N atoms of the macrocycle ligand and trans-N atoms derived from the nitrite anions. Systematic variations in the Co—N bond lengths are correlated with the presence of intramolecular N—H⋯O(nitrite) hydrogen bonds. In the crystal, water-O—H⋯O(perchlorate) hydrogen bonds, involving one of the independent perchlorate anions only, lead to supramolecular chains along the b-axis direction. The three-dimensional architecture is consolidated by numerous C—H⋯O interactions. The crystal studied was a non-merohedral, racemic twin.
