Abstract

In the title compound, C(20)H(21)N(2) (+)·C(7)H(7)O(4)S(-)·H(2)O, the cation is nearly planar and exists in the E configuration. The cations and anions form individual chains along the b axis and are inter-connected by weak C-H⋯O inter-actions. The 4-methoxy-benzensulfonate anions are linked to water mol-ecules through O-H⋯O hydrogen bonds, forming a three-dimensional network. The crystal structure is further stabilized by a C-H⋯π inter-action involving the methoxy-phenyl ring. The sulfonate anion is also involved in a weak intra-molecular C-H⋯O inter-action which generates an S(5) ring motif.

Experimental. The low-temparture data was collected with the Oxford Cryosystem Cobra low-temperature attachment.
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.
