Synthesis, Spexctral and Thermal Studies of Some Dioxouranium(VI)Coordination Compounds of 4[N-(4-Hydroxy-3-Methoxybenzalidene)Amino]Antipyrine Semicarbazone and 4[N-(3,4,5-Trimethoxybenzalidene)Amino]Antipyrine Semicarbazone

摘要

In view of high coordination compounds formed by actinide metal ions , the present work describes the 8,9 and 10 -cordinated compounds of dioxouranium(IV)4[N-(hydroxy-3-methoxybenzalidene)amino]antipyrine semicarbazone(HMBAAPS)and 4[N-(3,4,5-trimethoxybenzalidene)amino]antipyrine semicrbazone(TMBAAPS)with the general composition UO_2X_2 centre dot 2L(X=Br~-, I~-, NCS~- or ClO_4~-)and UO_2X_2 centre L(X=NO_3~- or CH_3COO~- and L=HMBAAPS or TMBAAPS).Alkl these complexes were characterized through elemental, spectral and thermal studies
