Rhodamine 6G hexachloridostannate(IV) acetonitrile disolvate

R. Venkatraman, L. Sitole and F. R. Fronczek

Abstract top

In the title compound, bis({6-ethylamino-10-[2-(methoxycarbonyl)phenyl]-2,7-dimethylxanthen-3-ylidene}ethanaminium) hexachloridotin(IV) acetonitrile disolvate, (C27H29N2O3)2[SnCl6]·2C2H3N, the octahedral SnCl62- anion lies on an inversion center. The xanthene ring system is essentially planar, with an average deviation of 0.020 Å, and the substituent benzene ring forms a dihedral angle of 85.89 (2)° with it. The Sn-Cl distances are in the range 2.4237 (3)-2.4454 (3) Å. There are N-H...Cl hydrogen bonds between SnCl62- ions and rhodamine 6G cations as well as [pi]-[pi] stacking interactions between rhodamine 6G cations (interplanar distance of 3.827 Å).

Comment top

The excellent photo-physical properties of rhodamines are well known (Herz, 1974; Johnson & McGrane, 1993; Nguyen & Meyer, 1992), and recently metal complexes of rhodamine 6 G have been reported by several authors (Bhagavthy et al., 1993; Fun et al., 1997; Wang et al., 1997; Liu et al., 1998). The aggregative properties of cationic species of the dye were observed to be dependent on the anionic environment created by the metal ions. We have synthesized a rhodamine 6 G derivative, 9-[2-methoxycarbonyl)phenyl]-3,6-bis(ethylamino)-2,7-dimethylxanthylium hexachlorotin(IV) diacetonitrile solvate, (I), the structure of which is presented in this paper.

The structure of (I) consists of discrete SnCl62- anions lying on inversion centers, rhodamine 6 G cations and acetonitrile solvent molecules (Fig. 1). The xanthene ring of the cation is planar within an average deviation of 0.020 Å (maximum deviation is 0.045 (1) Å for C4), and the phenyl ring forms a dihedral angle of 85.89 (2)° with it. The C—N distances N1—C24 and N2—C26 are normal for this type of single bond, whereas C3—N1 and C11—N2 are much shorter, showing partial double-bond character; details are in the Table. A similar trend is observed in the other rhodamine 6 G cations (Wang et al., 1997; Liu et al., 1998).

Both hydrogen bonding between cations and anions and π-π stacking interactions between rhodamine 6 G cations exist. Parallel rhodamine ions related by the inversion center have an interplanar distance of 3.827 Å (Fig. 2), and are slipped such that their O1—C13 bonds exactly overlap.

Experimental top

Diphenyl tin dichloride (0.344 g, 1 mmol) was dissolved in 20 ml me thanol, and then 20 ml of methanol solution of rhodamine 6 G (0.479 g, 1 mmol) was added. The bright red solution was refluxed for 1 hr, whereafter red brown solid were obtained on cooling. Suitable size crystals were obtained by the recrystallization at room temperature from acetonitrile (yield ca 85%).

Refinement top

H atoms were placed in idealized positions with C—H distances at 0.99, 0.98 and 0.95 Å for CH2, CH3 and aromatic CH groups, respectively using a riding model. Uiso for H was assigned as 1.2 times Ueq of the attached C atoms (1.5 for methyl); a torsional parameter was refined for each methyl group. The largest positive and negative residual density peaks were located within 1 Å of the Sn1 position.

Special details top

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.
