Tetragonal polymorph of 5,5-dichlorobarbituric acid
The tetragonal polymorph of 5,5-dichlorobarbituric acid (m.p. 478 K), C(4)H(2)Cl(2)N(2)O(3), forms an N—H⋯O hydrogen-bonded tape structure along [001]. Two tapes related by a twofold rotation axis are associated via Cl⋯O contacts [3.201 (1) Å], and four such chain pairs are arranged around a fourf...
