Synthesis, Spectral 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†

Abstract

In view of high coordination compounds formed by actinide
metal ions, the present work describes the 8, 9 and 10-coordinated
compounds of dioxouranium(IV) with 4[N-(4-hydroxy-3-methoxybenzalidene)
amino] antipyrine sernicarbazone (HMBAAPS] and
4[N-(3,4,5-trimethoxybenzalidene) amino] antipyrine semicarbazone
(TMBAAPS) with the general composition UO₂X₂·2L
(X = Br^-,  I^-,  NCS^- or CIO₄^-) and UO₂X₂·L (X = NO₃^-) or
CH₃COO^- and L = HMBAAPS or TMBAAPS). All these complexes
were characterized through elemental, spectral and thermal .
studies.
