Three lanthanide-based coordination compounds with 5-[N-acetato(4-pyridyl)]tetrazolate.

Reaction of 5-[N-acetato(4-pyridyl)]tetrazolate (a4-ptz) potassium salt with lanthanide(III) chlorides, produced three new coordination compounds, [Ln(a4-ptz)2(H2O)4]·Cl·2H2O (Ln = La(1), Eu(2) and Tb(3)). These compounds were characterized by elemental analysis, IR spectroscopy, and single-crystal X-ray diffraction. Complexes1–3displayed 1-D structures. Luminescences of1–3were investigated at room temperature in the solid state. [ABSTRACT FROM AUTHOR]
