Abstract
The crystal structure of the title compounds KH(AcO)2 has been determined by X-ray analysis and solved by the heavy-atom method. Z= 4 in a monoclinic unit cell of dimensions a= 4·085, b= 23·84, c= 7·226 Å, β= 97·4°, space group is P21/n. Refinement by anisotropic least-squares analysis has led to a final R of 0·106 for 849 data. This acid salt proves to be of Type B, i.e. the residues AcOH and AcO– are crystallographically distinct; these residues are linked through a short unsymmetrical hydrogen bond, with O O 2·476(8)Å.Keywords
