چکیده

In the mononuclear salen-type complex, [Er(NO(3))(3)(C(18)H(20)N(2)O(4))], the Er(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 salen-like ligand. Inter-molecular N-H⋯O hydrogen bonds occur. The crystal structure is stabilized by inter-molecular C-H⋯O hydrogen bonds.

The asymmetric unit of the title compound, [Er(NO(3))(3)(C(10)H(8)N(2))(2)], contains one-half mol-ecule situated on a twofold rotation axis. The Er(III) ion is in a tenfold coordination by six O atoms from three NO(3) (-) anions and four N atoms from two 2,2'-bipyridine ligands in a distorted bicapped dodeca-hedral geometry. In the crystal, weak C-H⋯O hydrogen bonds hold the mol-ecules together.
