Structural, optical and magnetic properties of a new metal-organic Co-based complex.

A mononuclear cobalt(ii) complex [CHN][CoCl(CHN)] (I) was synthesized and structurally characterized. Single crystal X-ray diffraction analysis indicates that monometallic Co(ii) ions acted as coordination nodes in a distorted octahedral geometry, giving rise to a supramolecular architecture. The latter is made up of a ½ unit form composed of an anionic element [CoCl(CHN)] and one 2-amino-4-methylpyrimidinium cation [CHN].
