The title compound, C33H34N4O2S·CH3OH, was prepared as a spirolactam ring formation of rhodamine 6 G dye for comparison with a ring-opened form. The xanthene and spirolactam rings are approximately planar [r.m.s. deviations from planarity = 0.122 (3) and 0.072 (6) Å, respectively]. The dihedral angles formed by the spirolactam and thiophene rings with the xanthene ring system are 89.7 (6) and 86.5 (2)°, respectively. The features N—H⋯O and C—H⋯O hydrogen bonds.

A portion of N-(rhodamine-6 G)lactam-ethylenediamine (228 mg, 0.5 mmol) and thiophenecarboxaldehyde (57.7 mg, 0.6 mmol) were combined in fresh distilled acetonitrile (50 ml). The reaction solution was refluxed for 24 h under N2 atmosphere. After that, the solution was cooled (concentrated to 10 ml) and allowed to stand at room temperature overnight. The precipitate which appeared next day was filtered and the crude product was purified by recrystallization from acetonitrile to give 247.6 mg of the title compound in 90% yield. Single crystals suitable for X-ray measurements were obtained from reaction mother liquid by slow evaporation at room temperature.
The H atoms attached to C, N and O atoms were placed in geometrically calculated positions (C—H = 0.93–0.97 Å and O—H = 0.82 Å) and refined as riding, with Uiso(H) = 1.2Ueq(C, N) or 1.5Ueq(methyl C, O).

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. |

Among many fluorescent compounds, rhodamine dyes are known to have excellent photophysical properties, and they are one of the most widely used fluorophores for labeling and sensing biomolecules. There are a few single-crystal reports about rhodamine derivatives bearing a lactam moiety (Xu et al., 2009; Xi et al., 2011; Xu et al., 2011; Wu et al., 2007; Xu, Zhang et al., 2010; Xu, Guo et al., 2010; Zhang et al., 2008; Tian et al., 2008;). Detailed information on their molecular and crystal structures is necessary to understand their photophysical and photochemical properties.
In agreement with other reported models, (Xu et al., 2009; Wu et al., 2007; Zhang et al., 2008; Tian et al., 2008; Xi et al., 2011;) the main skeleton of the molecule is formed by the xanthene ring and the spirolactam-ring. As shown in Figure 1, The atoms of the xanthene ring or the spirolactam-ring are both nearly planar and are almost perpendicular to each other. The dihedral angle between the xanthene mean planes and the spirolactam ring fragment is 89.7 (6)°. The dihedral angle between the xanthene mean planes and the thiophene ring is 86.5 (2)°.
