Basic zinc acetate

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... [Pg.1160]

The tetranuclear structure observed for basic zinc/acetate/[Zn40(02CCH3)6] is also observed for basic zinc pivalate and benzoate. Solution studies showed an equilibrium between hydrated basic structures and the hydrated form of 3,1 bridging structures in the presence of a trace amount of water. Zinc crotonate shows a less common basic carboxylate polymeric structure, [Zn5(OH)2 (02CCHCHCH3)8]n.369... [Pg.1176]

For the preparation of basic zinc acetate, Zn40 (CjH Oz) , see reference 3. The zinc compound is more readily hydrolyzed than the beryllium analogue. [Pg.41]

Figure 9.42 Secondary Building Units (SBU) using carboxylates with rigid coordination geometries that replace metal ions as vertices in MOFs. (a) Paddlewheel or lantern structure as in 9.17, (b) octahedral basic zinc acetate SBU used in MOF-5 and (c) a trigonal prismatic oxo-centred trimer. The poly-hedra use carboxylate carbon atoms as their vertices and the MOFs propagate via the linkers attached to these carbon atoms. The metal atoms are bound to only terminal ligands in addition to those shown.

Zn(NH3)6]" exists in equilibrium with tetrahedral [Zn(NH3)4] +. Equation 9.25 showed the formation of [Zn(NH2)4]. Basic zinc acetate [Zn4(ii4-0)(p-02CMe)6] is isostructural with its Be(II) analogue (Figure 12.6), but is more readily hydrolysed in water. Another salt of interest is Zn(acac)2 H20 (22.71) in which the coordination of... [Pg.740]
