Question

what is the coordination number and geometry of [UO2(NO3)3]-​

Answer 1

Explanation:

The UV-Vis absorption spectra of complexes exhibiting a trigonal D3h coordination symmetry like [UO2(NO3)3]- and [UO2(CH3COO)3]-, both formed in organic solvents, are characterized by very sharp, intense peaks at the low energy side of the spectrum, i.e. between 21000 cm-1 and 24000 cm-1.
