摘要：
Compound [Co(NioxH)(2)(PPh3)(2)]F is synthesized in the CoF2 (.) 4H(2)O-NioxH(2)-PPh3 system (where NioxH is the 1,2-cyclohexanedione dioxime monoanion and PPh3 is triphenylphosphine), and its structure is determined by X-ray diffraction. It is shown that the cobalt atom has the octahedral environment. Two nioxime residues that are related by the center of symmetry lie in the equatorial plane and are linked by the O-(HO)-O-... hydrogen bond. The 1,6-positions of the octahedron are occupied by the phosphorus atoms of the triphenylphosphine ligands. The formation of the crystal structure of this compound is discussed.
