چکیده
In the title mononuclear Schiff base complex, [Dy(NO(3))(3)(C(18)H(20)N(2)O(4))], the Dy(III) ion is ten-coordinated in a distorted hexa-deca-hedral geometry by six O atoms of three nitrate anions and four O atoms of the Schiff base ligand. An intra-molecular N-H⋯O hydrogen bond occurs. The crystal structure is stabilized by inter-molecular C-H⋯O hydrogen bonds.

In the title mononuclear salen-type complex, [Eu(NO(3))(3)(C(22)H(26)N(2)O(4))]·CH(3)OH, the Eu(III) ion is ten-coordinated by three bidentate nitrate counter-ions and one organic salen-type ligand, which acts in a bis-bidentate chelating mode through its phenolate and meth-oxy O atoms. The protonated imine groups are involved in intra-molecular N-H⋯O hydrogen bonds to the phenolate O atomss, e...
