Both molecules adopt a trans–cis configuration with respect to the positions of the hexanoyl and 6-methyl-2-pyridyl groups relative to the S atom across their C—N bonds. In the crystal structure, the molecules are linked by intermolecular N—H⋯S and C—H⋯O hydrogen bonds to form a molecular tape running along the [310] direction.
The bond distances and angles (Table 1 [link] ) are normal (Orpen et al., 1989 [ Orpen, AG, Bramm... more The bond distances and angles (Table 1 [link] ) are normal (Orpen et al., 1989 [ Orpen, AG, Brammer, L., Allen, FH, Kennard, O., Watson, DG & Taylor, R.

The average Zn-O distance of 2.02 (2) Å is in agreement with the geometry of square pyramidal and trigonal bipyramidal, compared with 1.98 Å for tetrahedral (Morgant et al., 1998 [Morgant, G., ...
