A new series of donor‐stabilized addition complexes of cobalt(II) with disubstituted diphenyldithiophosphates [{(ArO) 2 PS 2 } 2 Co L 2 ] {Ar = 2,4‐(CH 3 ) 2 C 6 H 3 [(1)–(3)] and 3,5‐(CH 3 ) 2 C 6 H 3 [(4)–(6)]; L = C 5 H 5 N [(1), (4)], 3,4‐(CH 3 ) 2 C 5 H 3 N [(2), (5)] and 4‐(C 2 H 5 )C 5 H 4 N [(3), (6)]} were successfully isolated and characterized by elemental analyses, magnetic moment measurements, IR and single‐crystal X‐ray analysis. Complexes (3), (4) and (5) crystallize in the monoclinic space groups P 2 1 / n , P 2 1 / n and P 2 1 / c , respectively, whereas complex (6) crystallizes in the triclinic space group . X‐ray diffraction analysis of complexes (3)–(6) reveals a six‐coordinated distorted octahedral geometry for the CoS 4 N 2 chromophore defined by two chelating diphenyldithiophosphate anions as well as two N‐donor ligands. Two diphenyldithiophosphate ligands are coordinated to the cobalt ion as a bidentate ligand chelating via the two thiolate S atoms. Each of them forms a four‐membered chelate ring in the equatorial plane. The N atoms from two donor ligands are axially coordinated to the Co atom in a mutually trans position.
