Synthesis, Magneto-Spectral and Thermal Characteristics of Some 7-Coordinated Compounds of Lanthanides(III) Chlorides with 4[(Furan-2-ylmethylene)amino]-1,5-dimethyl-2-phenyl pyrazol-3-one and Isonicotinic acid(30 ,40 ,50 -trimethoxybenzylidene)hydrazide

Abstract
In the present work, we describe the isolation of some lanthanide(III) chlorides coordination compounds with 4[(furan-2-ylmethylene)amino]-1,5-dimethyl-2-phenyl pyrazol-3-one (FDPPO) and isonicotinic acid(3',4',5'-trimethoxybenzylidene)hydrazide (ITMBH) with the general composition [Ln(L)2Cl3] (Ln = La, Pr, Nd, Sm, Gd, Tb, Dy or Ho; L = FDPPO or ITMBH). All the isolated compounds were characterized through various physico-chemical studies. The coordinating ligands FDPPO or ITMBH act as neutral bidentate N and O-donors in the present compounds. The central metal ion displays the coordination number 7 in these complexes. Thermal stabilities of these complexes were also studied through thermogravimetric analysis.
