3,3′-Dibutanoyl-1,1′-(o-phenylene)dithiourea

The molecular conformation of the title compound, C16H22N4O2S2, is stabilized by two intramolecular N—H⋯O hydrogen bonds. The crystal packing shows N—H⋯O and N—H⋯S hydrogen bonds.


Experimental
Crystal data
Bis-thiourea resins have been used for adsorption of silver(I) and gold(II) for application to retrieval of silver ions from processed photo films (Atia et al., 2005). Diisoamyloxydiphenylthioureas are effective anti-tuberculosis agents (Phetsuksiri et al. (2003).
The molecular conformation of the title compound is stabilized by two N-H···O hydrogen bonds. The crystal packing shows N-H···O and N-H···S hydrogen bonds.

Experimental
The compound was prepared acc ording to lierature procedure (Succaw et al., 2005)

Refinement
H atoms attached to C were geometrically positioned and refined using a riding model with C-H(aromatic) = 0.95 Å, C-H(methyl) = 0.98 Å, or C-H(methylene) = 0.99 Å, respectively. The position of the amino H atoms were freely refined.

In all cases fixed individual displacement parameters
[U(H) = 1.2 U eq (C aromatic ), 1.2 U eq (N); 1.5 U eq (C methyl )] were used.  as those based on F, and R-factors based on ALL data will be even larger.
