Stereochemistry of some high coordination compounds of dioxouranium(VI) With thiosemicarbazones
( Qatar University , 1994 , Article)The UO2 ion is peculiar in its coordination behaviour, because of its inherent capacity of forming compounds with higher coordination number. In the present work we describe the synthesis of a series of eight, nine and ten ... -
