Si. Mostafa, Complexes of 2,5-dihydroxy-1,4-benzoquinone and chloranilic acid with second and third row transition elements, TRANSIT MET, 24(3), 1999, pp. 306-310
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.
