Darstellung und kristallographische Daten von Diamminzinkacetat, Zn(NH 3 ) 2 (OCOCH 3 ) 2

Zn(NH3)2(OCOCH3)2 crystallizes from solutions obtained by dissolving ZnO in a methanolic solution of ammonium acetate. The pycnometrically determined density is 1.824 g cm−3 at 23°C. From X-ray rotation photographs the dimensions of the monoclinic unit cell, containing eight formula units, were found to be:a=11.64±0.05,b=5.54±0.05,c=23.28±0.05 A, β=93.6±0.5°. The probable space group is C2/m-C2h3.
