Crystal Structure of 1-[4-(2,2-Diphenylacetyl)piperazin-1-yl]-3-buten-2-ol

Abstract

1-[4-(2,2-Diphenylacetyl)piperazin-1-yl]-3-buten-2-ol (1) crystallizes in the monoclinic space group P21/a with a = 18.057(1), b = 6.036(2), c = 19.309(1)A, β = 115.630(4)°, V = 1897.3(5)A3, Z = 4. The carbonyl group and the nitrogen of piperazine constitutes an almost planar amide moiety due to being conjugated with the carbonyl group. An intermolecular hydrogen interaction of the hydroxyl group to another nitrogen of piperazine (bond distance: 2.86(3)A) is present.
