In the crystal structure of the title compound, C14H12NS+·CF3SO3−, N—H⋯O hydrogen bonds link cations and anions into ion pairs. Inversely oriented ion pairs form stacks through multidirectional π–π inter­actions among the acridine units. The crystal structure features a network of C—H⋯O inter­actions among stacks and also long-range electrostatic inter­actions among ions. In the packing of the mol­ecules, the acridine units are nearly parallel in stacks or inclined at an angle of 33.07 (2)° in the four adjacent stacks with which they inter­act via weak C—H⋯O inter­actions. The methyl­sulfanyl group is twisted through an angle of 60.53 (2)° with respect to the acridine ring.

Comment top

Acridinium cations containing various substituents at position 9 and alkyl substitutes at the endocyclic N atom (position 10) are susceptible to oxidation by H2O2 or other oxidants in alkaline media, leading to the formation of electronically excited 10-alkyl-9-acridinones capable of emitting light with a quantum yield of several percent (Zomer & Jacquemijns, 2001; Wróblewska et al., 2004). The chemiluminescence phenomenon described above is governed by the features of the substituent at position 9. In the search for derivatives that could exhibit enhanced chemiluminescence, we turned our attention to compounds in which the C atom at position 9 is bound to the S atom. The simplest compound that we were able to synthesize was 9-(methylthio)acridinium trifluoromethanesulfonate. It was obtained by the reaction of 9-thioacridinone (Berny et al., 1992) with methyl trifluoromethanesulfonate, which usually leads to quarternarization of the endocyclic N atom (Sato, 1996). The cation of the reaction product has a protonated endocyclic N atom, enabling it to react with oxidants, thereby facilitating the investigation of chemiluminescence phenomena. This paper presents the crystal structure of the title compound. This is, to our knowledge, only the second report on the crystal structure of an acridine derivatives S-substitued at position 9 (for the first one, see Mrozek et al., 2002).

In the cations of the title compound (Fig. 1), the bond lenghts and angles characterizing the geometry of the acridine skeleton are typical of acridine-based derivatives (Storoniak et al., 2000; Meszko et al., 2002; Mrozek et al., 2002). The C9–S15 and S15–C16 bond lengths (1.754 (3) Å and 1.807 (4) Å, respectively) correlate well with those reported for 9-(thio-2'-methyl-4'-nitrophenyl)acridine (Mrozek et al., 2002). The C9–S15–C16 fragment and the acridine ring system, with an average deviation from planarity of 0.037 (4) Å, are oriented at 60.53 (2)° to each other. The acridine units in the lattice are either parallel (within stacks) or inclined at an angle of 33.07 (2)° (in four adjacent stacks with which they interact via C–H···O hydrogen bonds).

In the crystal structure, N–H···O hydrogen bonds (Aakeröy et al., 1992) link cations and anions in ion pairs (Table 1, Fig. 1). Inversely oriented ion pairs form stacks in which the central ring (Cg1) and the aromatic rings (Cg2 and Cg3) are involved in multidirectional π-π interactions (Table 2, Fig. 2) of an attractive nature (Hunter et al., 2001). The crystal structure is stabilized by a network of C–H···O hydrogen type bonding interactions (Steiner, 1991; Bianchi et al., 2004) between neighbouring stacks (Figs 2 and 3) as well as by long-range electrostatic interactions between ions.

Experimental top

9-(Methylthio)acridinium trifluoromethanesulfonate was synthesized in two steps. First, 9-thioacridinone was synthesized by heating with stirring a mixture of 9(10H)-acridinone, tetraphosphorus decasulfide and freshly distilled pyridine at 100°C for 1 h (Berny et al., 1992). The reactant mixture was subsequently poured into 30% aq ammonia and the resulting precipitate of 9-thioacridinone filtered off. This compound was then treated with a fivefold molar excess of methyl triluoromethanesulfonate dissolved in dichloromethane for 3 h (Ar athmosphere, room temperature) (Sato, 1996). The crude 9-(methylthio)acridinium trifluoromethanesulfonate thus formed was dissolved in a small amount of ethanol, filtered, and again precipitated with a 25 v/v excess of diethyl ether (yield: 87%). Yellow crystals suitable for X-ray investigations were grown from absolute ethanol solution (m.p. 421–423 K).

Refinement top

H atoms involved in C–H···O interactions were located in a difference map and refined without constrains. H atoms involved in N–H···O interaction were located in a difference map and refined using the N—H distance restraint of 0.86 (2) Å. Other H atoms were positioned geometrically, with C—H = 0.93 Å (aromatic) and 0.96 Å (methyl), and constrained to ride on their parent atoms with Uiso(H) = 1.2Ueq(C) (aromatic) or Uiso(H) = 1.5Ueq(C) (methyl).

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.

Symmetry codes: (ii) -x, -y+2, -z+1; (iii) -x+1, -y+2, -z+1. Notes: Cg1, Cg2 and Cg3 are the centroids of the C9/N10/C11–C14, C1–C4/C11/C12 and C5–C8/C13/C14 rings, respectively. Cg···Cg is the distance between ring centroids. The dihedral angle is that between the planes of the rings CgI and CgJ. The interplanar distance is the perpendicular distance of CgI from ring J. The offset is the perpendicular distance of ring I from ring J.
