Beryllium butyrate, basic, properties and structure of, 3 7, 8 Beryllium carbonate, basic, for use in preparation of basic beryllium acetate, 3 10 Beryllium chloride, anhydrous, 6 22 Beryllium o-chlorobenzoate, basic, properties of, 3 7 Beryllium complex compounds, basic, of organic acids, 3 4 basic, structure of, 3 6 nonelectrolytes, with acetylace-tone, Be(CsH702)2, 2 17 with benzoylacetone, Be(Cio-H 02)2, 2 19... 

I herc is also an interesting series of basic beryllium complexes with the carboxylic acids which are covalent compounds of remarkable stability. Basic beryllium acetate, Be40(00C.CH3)g melts at 283°, boils at 330° without decomposition and dissolves in CHCI3 as the monomer it lacks ionic properties. Its structure has a central O atom surrounded tetrahedrally by tour... 

When solutions of beryllium salts are brought together with red-violet solutions of quinalizarin [1,2,5,8-tetrahydroxyanthraquinone (I)] in am-moniacal or caustic alkali solution, a blue-violet precipitate or color appears. Although quinalizarin, as a derivative of alizarin, is a lake-forming dyestuff, which produces red to red-violet adsorption compounds with oxyhydrates of aluminum, zirconium, thorium, etc., its beryllium reaction product seems to be a stoichiometrically defined compound rather than an adsorption complex. In conformity with the fact that the blue product contains two atoms of beryllium combined with one molecule of quinalizarin, it seems proper to view the material as a basic beryllium salt with the structure (II) or (Ila) ... 

The zinc complex formed with V,V -diphenylformamidinate is structurally analogous to the basic zinc acetate structure, as [Zn4(/i4-0)L6], and the basic beryllium acetate structure. It is prepared by hydrolysis of zinc bis(diphenylformamidinate).184 Mixed metal zinc lithium species were assembled from dimethyl zinc, t-butyl lithium, V.iV -diphenylbenzamidine and molecular oxygen. The amidinate compounds formed are dependent on the solvent and conditions. Zn2Li2 and... 

Its chelate compounds include acetylacetonc and dioxalato complexes, and a basic acetate, Zn40( H3 00)g, very similar in properties to that of beryllium (p. 263), with a tetrahedral structure centred on the oxygen atom.
