  "abstract": "A cobalt(III) complex [Co(L)2]Cl PPO H2O (1) (HL = 1-(2-aminobenzylimino)-1-phenyl-propan-2-one oxime, PPO = 1-phenyl-1,2-propanedione-2-oxime) has been synthesized and characterized by elemental analyses, spectral, thermal, magnetic and molar conductance measurements and single crystal X-ray diffraction. It crystallizes in the monoclinic crystal system, space group P21/c. Complex 1 consists of one uncoordinated water, one 1-phenyl-1,2-propanedione-2-oxime molecule, one bis[1-(2-aminobenzylimino)-1-phenyl-propan-2-one oxime]cobalt(III) cation and one uncoordinated chloride. The coordination geometry around Co is slightly distorted octahedral, completed with six nitrogens of two L- ligands. The oxime moieties have E configurations. In the crystal structure, intramolecular O-HCl and N-HO and intermolecular N-HO, O-HCl and N-HCl hydrogen bonds link the molecules into chains parallel to the c axis; hydrogen-bonded PPO molecules fill the spaces between the chains and stabilization of the structure.",
