(Received 31 July 2009; accepted 17 August 2009; online 22 August 2009)

In the cation of the title salt, C11H12ClN2O+·C6H2N3O7−, the chloro­ethyl side chain is in a syn conformation, nearly orthogonal to the pyrimidine ring, with a dihedral angle of 78.9 (6)° between the plane of the chloro­ethyl chain and the pyrimidine ring. The dihedral angle between the fused rings is 4.3 (3)°. In the picrate anion, the benzene mean plane makes dihedral angles of 26.7 (1), 33.6 (2) and 5.3 (6)° with the two o-NO2 groups and the p-NO2 group, respectively. Extensive hydrogen-bond inter­actions occur between the cation–anion pair which help to establish the crystal packing. A three-center O⋯(H,H)—(N,C) acceptor hydrogen bond is observed between the phenolate O atom of the picrate anion and the amine and methyl groups of the cation. An N—H⋯(O,O) bifurcated hydrogen bond is observed between the amine group and two O atoms from the phenolate and o-NO2 groups.

Comment top

We have recently reported the crystal structure of 3-(2-chloroethyl)-2-methyl-4H-pyrido[1,2-a]pyrimidin-4-one (Jasinski et al., 2009) which is an intermediate in the synthesis of risperidone, and is a potent antipsychotic agent, especially useful for treating schizophrenia (Gabbert & Giannini, 1997). The present paper reports the interaction of 3-(2-chloroethyl)-2-methyl-4H-pyrido [1,2-a]pyrimidin-4-one as an electron donor with picric acid as electron acceptor which resulted in the formation of a charge transfer complex of title compound, (I), C17H14ClN5O8.

The title compound, C11H12ClN2O+.C6H2N3O7-, a picrate salt of 3-(2-chloroethyl)-2-methyl-4H-pyrido[1,2-a]pyrimidinium-4-one, crystallizes with one independent cation-anion pair in the asymmetric unit (Fig. 1). In the cation, the chloroethyl side chain is in a syn conformation [-sc, C1A—C2A—C10A—C11A = -78.29 (16)°], nearly orthogonal to the pyrimidine ring, with a dihedral angle of 78.9 (6)° between the chloroethyl side chain and the pyrimidine ring. The fused pyrimidine-pyridine ring is separated by 4.3 (3)°. In the picrate anion, the benzene ring adopts dihedral angles of 26.7 (1), 33.6 (2) and 5.3 (6)° with the mean planes of two o-NO2 and a p-NO2 group, respectively. Extensive hydrogen bond interactions occur between the cation-anion pair which help to establish crystal packing (Fig. 2). This includes a strong N4A—H4AA···O1B hydrogen bond and a collection of several weak C—H···O interactions within several sites between the cations and anions in the unit cell (Table 1). A three-center O···(H,H)-(N,C) acceptor hydrogen bond is observed between the phenolate oxygen atom (O1B) of the picrate anion and the amine (H4AA) and methyl group (H12C) hydrogen atoms of the pyrimidine group in the cation. A bifurcated (three-center) N—H···(O,O) hydrogen bond is observed between the amine hydrogen atom (H4AA) in the pyrimidine group and oxygen atoms from the phenolate (O1B) and o-NO2 (O62B) groups. Included in this bond is a weak N4A—H4AA···O62B interaction (Table 1). Bond lengths and angles in both the cation and anion can be regarded as normal (Cambridge Structural Database, Version 5.30, February, 2009; Allen, 2002, Mogul, Version 1.1.3; Bruno et al., 2004) The collective effects of both strong and weak intemolecular hydrogen bonds influence crystal packing in the title compound, C11H12ClN2O+.C6H2N3O7-, (I).

Experimental top

The title compound was synthesized by adding a saturated solution of picric acid (0.92 g, 2 mmol) in methanol to a solution of 3-(2-chloroethyl)-2-methyl-4H-pyrido[1,2-a]pyrimidin-4-one (0.45 g, 2 mmol) in 10 ml of methanol. A yellow color developed and the resulting solution was stirred well with the formation of yellow precipitate which was filtered off, washed several times with diethyl ether and then dried over CaCl2 (yield 64.5%). X-ray quality crystals were grown from acetone solution. The melting range was found to be 415–418 K.

Refinement top

All of the H atoms were placed in their calculated positions and then refined using the riding model with N—H = 0.88 Å, C—H = 0.95–0.99 Å, and with Uiso(H) = 1.17–1.48Ueq(C,N).

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.
