چکیده
The title complex, [Er(C(32)H(16)N(8))(C(5)H(7)O(2))(C(12)H(8)N(2))], possesses a mirror plane and the asymmetric unit is half of the mol-ecule. The Er(III) cation, lying on the mirror plane, is eight-coordinated by two O atoms from acetyl-acetone, two N (N(phen)) atoms from 1,10-phenanthroline and four isoindole N (N(iso)) atoms from the phthalocyanine ligand in an anti-prismatic geometry. The Er-N distances are in the range 2.376 (5)-2.529 (4) Å and the Er-O distance is 2.272 (3) Å. Notably, the Er-N(iso) bonds are shorter than the Er-N(phen) bonds, but longer than the Er-O bonds.

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.
