Figure 5.4 The molecular structure of basic beryllium acetate showing (a) the regular tetrahedral arrangement of 4 Be about the central oxygen and the octahedral arrangement of the 6 bridging acetate groups, and (b) the detailed dimensions of one of the six non-planar 6-membeted heterocycles. (The Be atoms are 24 pm above and below the plane of the acetate group.) The 2 oxygen atoms in each acetate group are equivalent. The central Be-O distances (166.6 pm) are very close to that in BeO itself (165 pm).

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...

Diethylzinc reacts with dimethyltriazene to afford the moisture-sensitive complex Zn(MeNNNMe)2 (17). However, a similar reaction involving diphenyltriazene gave a product which, after recrystallization from dry benzene, was found to be Zn40(PhNNNPh)g and to possess a basic beryllium acetate type of structure (48). 

It is of particular interest to compare the hydrolytic behavior of basic beryllium nitrate, Be40(N03)e. This compound (15) has the structure which is already well known for basic beryllium acetate each nitrate group is part of a six-membered ring... 

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...

Basic beryllium acetate, Be40 (CH3 COO) 5, has the properties of a molecular soUd rather than an ionic salt. The crystal structure is cubic, with a = 15.74 A and Px = 1.39 g cm . The diffraction (Laue) symmetry is m3 and only the following reflections are observed ... 

Be40(02CCH3)e. The acetate is typical of the basic beryllium carboxylates (Be(OH)2 plus ethanoic acid). The structures have O at the centre of a tetrahedron of Be with carb-oxylate spanning each edge of the tetrahedron. Be(02CCH3)2 is formed from BeCl2 and glacial ethanoic acid.
