Abstract

Two rare earth coordination complexes, [Dy(DAPBH)NO₃(H₂O)₂]⋅(NO₃)₂ (1), La(DAPBH)(NO₃)₃ (2) (where DAPBH = 2, 6-diacetylpyridine benzoyhydrazone), have been synthesized and characterized. Single crystal structural analysis revealed that the Dy³⁺ ion is nine-coordinated with three N-atoms and two O-atoms from pentadentate DAPBH ligand, two O-atoms from one nitrate and other two O-atoms from two water molecules, and the coordination sphere features as a capped tetragonal antiprism in 1, while the La³⁺ ion is bound to six O atoms from three nitrate counter ions, three N-atoms and two O-atoms from a pentadentate DAPBH ligand to form a tricapped tetragonal antiprism coordination geometry in 2. Variable-temperature magnetic susceptibility measurements showed the existence of weak antiferromagnetic interaction in 1.
