In the title compound, C10H18N3OS+·Cl−·2H2O, the three C atoms of the isopropyl group are disordered and were refined using a split-site mode [occupancy ratio 0.53 (3):0.47 (3)]. In the crystal, the cations, anions and water molecules are connected via O—H⋯O, O—H⋯Cl, N—H⋯Cl and N—H⋯O hydrogen bonding.

The title compound was synthesized according the reported procedure of Li et al.(2007). Colorless single crystals were obtained by slow evaporation of a solution in acetone.
The C—H H atoms were placed in ideal positions and were refined using a riding model. with C—H=0.98–1.00Å and Uiso(H)=1.2Ueq(C) (1.5 for methyl H atoms). The N—H and O—H H atoms were refined with varying coordinates isotropic with Uiso(H) = 1.2Ueq(N) =1.5Ueq(O). The isopropyl group is disordered and were refined using a split model with restrained distances and s.o.f. of 0.54 (3) and 0.46 (3). The
was determined on the basis of 1535 Friedel pairs.Data collection: CrystalClear (Rigaku/MSC, 2005); cell

Geometry. All e.s.d.'s (except the e.s.d. in the dihedral angle between two l.s. planes) are estimated using the full covariance matrix. The cell e.s.d.'s are taken into account individually in the estimation of e.s.d.'s in distances, angles and torsion angles; correlations between e.s.d.'s in cell parameters are only used when they are defined by crystal symmetry. An approximate (isotropic) treatment of cell e.s.d.'s is used for estimating e.s.d.'s involving l.s. planes. |
Refinement. Refinement of F2 against ALL reflections. The weighted R-factor wR and goodness of fit S are based on F2, conventional R-factors R are based on F, with F set to zero for negative F2. The threshold expression of F2 > σ(F2) is used only for calculating R-factors(gt) etc. and is not relevant to the choice of reflections for refinement. R-factors based on F2 are statistically about twice as large as those based on F, and R- factors based on ALL data will be even larger. |

N-substituted thiomorpholine derivatives are considered as a potential dipeptidyl peptidase IV(DPP-IV) (Engel et al., 2003) inhibitor. These compounds present various biological properties, for instance, effectively ameliorate hyperglycemia,hyperlipidemia and significantly increase β-cell mass and improve islet architecture (Mu et al., 2006). In Addition, DPP-4 inhibitors display a potential anti-HIV-1 activity (Proost et al., 1998). The crystal structure of the title compound was analyzed by X-ray diffraction to investigate its structure-activity relationships.
In the crystal structure molecule of the title compound (Fig.1) the cations and anions are linked via intermolecular N—H···Cl interactions. They are additionally connected to the crystal water molecules by N—H···O and O—H···Cl interactions (Fig. 2 and Table 1). The water molecules are linked by strong O—H···O hydrogen bonding into zigzag-chains that elongate in the direction of the crystallographic c axis (Fig. 2).
