A metal complex of general formula Cr(II)-C26H14N8 has been obtained as an amorphous compound and studied by means of IR and Energy Dispersive X-ray Diffraction (EDXD).

Abstract
A metal complex of general formula Cr(II)-C26H14N8 has been obtained as an amorphous compound and studied by means of IR and Energy Dispersive X-ray Diffraction (EDXD). The chemical composition and the IR signals of the sample suggest that the hemiporphyrazine is bound to the metal atom via nitrogen atoms. EDXD data confirm this finding and show that the compound structure is composed of two parallel stacks of seven planar macro-molecules. The second stack is rotated by 5° around the z axis originating in its center of mass and the molecules are lying on parallel planes to xy plane.
