Abstract

Abstract : The crystal structures of two classical cobalt(III) complexes comprising the [CoCl(NH3 )(en)(py)2 ] 2+ cation were determined by single‐crystal X‐ray diffraction. Both complexes, dark red [CoCl(NH3 )(en)(py)2 ]Cl2 · H2 O (1 ) and purple [CoCl(NH3 )‐(en)(py)2 ][HgCl4 ]· 1.125H2 O (2 ), crystallize in the triclinic space group P 1 . In both compounds, the Co atom exhibits a typical octahedral coordination and the configuration index of the complex is OC‐6‐43. In the case of the chloride (1 ), the asymmetric unit comprises one formula unit, whereas there are two formula units in the case of the tetrachloridomercurate (2 ). Complex cations, anions, and crystal water molecules are interconnected by various N–H··· N, N–H··· Cl, N–H··· O, O–H··· Cl, and O–H··· O bridge bonds. As a result, compound1 features a two‐dimensional layer structure and compound2 exists as a three‐dimensional network. Abstract :
