Abstract
The synthesis of new 2,5-dihydroxy-1,4-benzoquinone (H(2)DHBQ) and chlorani lic acid (H(2)CA) complexes cis-[Mo2O5L2](2-) (L = DHBQ, CA), [W2O5(DHBQ)(2 )](2-), [WO2(CA)(2)](2-), trans-[UO2(DHBQ)]. H2O, and trans-[UO2(CA)(2)](2- ) is described. Raman, i.r., H-1 and C-13 n.m.r spectra of the ligands and their complexes are reported and their structures discussed.
