N'-Benzoyl-N,N-diethyl-thio-urea: A monoclinic polymorph

Abstract

In the crystal of the title compound, C12H16N 2OS, inversion dimers linked by pairs of N - H⋯S hydrogen bonds occur, generating R 2 2(8) loops. The mol-ecules are also linked by weak C - H⋯O hydrogen bonds. The structure is isostructural with that of N'-benzoyl-N,N-diethyl-seleno-urea [Bruce et al. (2007). New J. Chem. 31, 1647-1653].
