X-ray structure and magnetochemical study on a Co(II) complex of 2-acetyl-1,3-indandione

An X-ray structure of a Co(II) complex of bidentate chelating 2-acetyl-1,3-indandione (2AID) is reported–Co(2AID)₂(H₂O)₂ · 2H₂O. The compound crystallizes in the monoclinic space group P2₁/n with four molecules per unit cell. The molecular structure shows distorted octahedral geometry of the metal center. The complex is characterized by EPR and magnetic measurements, which show high-spin electronic structure for the metal ion.
