Cadmium oxide coordination number

Other X-ray spectroscopic studies include cadmium adsorption on aluminum oxides (Papelis et al. 1995), where it was found that Cd-O distances and coordination numbers (6 oxygens) on two aluminas agree with Cd-O distances and coordination in aqueous solutions. In low sorption density samples, absence of cadmium... 

A number of zinc and cadmium complexes of adenine (82),554,555 adenine N-oxide,556 guanine,557 inosine,558 cytidine559 and other nucleosides560 have been studied. The structure of (9-methyladenine)ZnCl2 is polymeric each zinc ion is tetrahedrally coordinated to two chlorine atoms (Zn—Cl = 2.22 A), and to N-l and N-7 of neighbouring adenine moieties (Zn— N = 2.05A).561 A structural study of the related cadmium complex, CdCl2(DMSO)L (L = 9-methyladenine), has shown the complex to form a one-dimensional polymer. 2... 

This is true only for silver(I), mercury(II), gold(I), and possibly cadmium and lead ions. At the pH of the ocean, hydroxide coordination is important for all ions having an oxidation number greater than 2 ( 36, 37).
