Abstract: | The title compound, Co(C9H10NO3)2(C2H8N2)]Cl·4H2O, is one of six possible diastereomers of the (1,2‐diaminoethane)bis(S‐tyrosinato)cobalt(III) complex. The cobalt(III) ion has an octahedral coordination, with three five‐membered chelate rings which have deformed coordination angles and coordinated O atoms in trans positions. In comparison with the previously reported crystal structure of the Δ‐C1‐cis(O) diastereomer Miodragovi?et al. (2001). Enantiomer, 6 , 299–308], the compound presented in this paper has more planar five‐membered aminocarboxylate rings. Complex cations, chloride anions and water molecules of crystallization are linked together by a network of hydrogen bonds. The chloride anions lie approximately between two Co atoms and form hydrogen bonds with all coordinated NH2 groups. In the crystal structure, there is a weak intermolecular π?π interaction between the phenyl rings. |
