N-Methyl-1-oxoisoindoline-2-carboxamide monohydrate

B. Maliha, M. I. Tariq, M. N. Tahir, I. Hussain and H. L. Siddiqui

Abstract top

The title compound, C10H10N2O2·H2O, is dimerized by inversion-related intermolecular N-H...O hydrogen bonding. There is an intramolecular N-H...O bond, resulting in a six-membered ring. Each dimer interacts with other dimers through hydrogen bonding with water molecules. The water molecules are linked to each other in a stair-like chain, thus generating two-dimensional polymeric strips. The dimers are also linked to each other through intermolecular C-H...O hydrogen bonding. There are [pi]-[pi] interactions between the aromatic and heterocyclic five-membered rings [centroid-centroid distance 3.8360 (12) Å]. C-H...[pi] interactions also exist between CH2 groups and aromatic rings.

Comment top

Isoindole and their derivatives are known to be active-compounds pharmaceutically (Straub et al., 2007; Mancilla et al., 2007). They are important intermediates in the synthesis of novel multi-drugs resistance reversal agents (Berger et al., 1999). They show diuretic, anti-anginal, cardio-vascular and herbicidal activitities (Alberto et al., 1994; Cignarella et al., 1981; Toru et al., 1986).

The title compound (I) is in continuation to the synthesis of various isoindoles and the determination of their structures by X-ray crystallography (Maliha et al., 2007; 2008). It was isolated during the studies of the reaction of urea and its N-alkyl/aryl derivates with o-phthaldehyde.

The present structure shows that replacing the H-atom of 1-Oxoisoindoline-2- carboxamide (Maliha et al., 2008) with CH3 group, is possible in the presence of crystallization water only. The replacement of H-atom of 1-Oxoisoindoline-2-carboxamide with ethyl group (Wan et al., 2007) also shows the existence of crystallizing H2O. Although the bond distances and bond angles in the aromatic A(C2—C7) and five-membered ring B(C1/C2/C7/C8/N1) are comparable with the reported structures (Maliha et al., 2008; Wan et al., 2007), but the packing through H-bonding is entirely different. There is an intramolecular hydrogen bond of N2—H2···O1 resulting in a six-membered ring. The title compound is dimerized by inversion of N-methyl-1-oxo-1,3-dihydro-2H-isoindole-2-carboxamide through intermolecular H-bond viz N2—H2···O1i [symmetry code i = -x,-y,-z] and the central ring is of four members depending upon these H-bonds only. The role of H2O molecules is to stabilize the dimers through an interesting H-bonding. The H-bond O3—H1W···O2ii [symmetry code ii = x + 1, y, z] connects the dimers, while the O3—H2W···O3iii [symmetry code iii = x, -y + 1/2, z - 1/2] joints the water molecules in a stair like chain. In this way two-dimensional polymeric strip is realized. These polymeric strips are further connected by the involvement of aromatic ring A(C2—C7) through intermolecular H-bonds C4—H4···O2iv [symmetry code iv = x + 1, y, z - 1]. The detail of H-bonding is given in Table 1 and shown in Fig. 2. The π-π interaction exist between the CgA···CgBv [symmetry code v = x,y,z - 1] and CgB···CgAvi [symmetry code vi = x,y,z + 1] having same centroid-centroid distance of 3.8360 (12) Å. The C—H···π interaction exists between C8—H8A and CgAvi [symmetry code vi = x,y,z + 1] with H8A···π distance of 2.86 Å.

Experimental top

A mixture of o-phthaldehyde (0.67 g, 200 mmol) and N-methylurea (0.37 g, 200 mmol) in 100 ml of ethanol was refluxed for 10 h. The solvent was taken off and flask contents were left at room temperature. The crystals of (I) were isolated, washed with ethanol, ether and n-hexane, respectively and dried. Crystals suitable for X-ray diffraction were grown from a mixture of methanol-acetone (1:1) by slow evaporation at room temperature. It is soluble in DMSO, DMF, acetone, ethyl acetate, chloroform and carbon tetrachloride. M.P: 413 K; yield: 60 percent.

Refinement top

H atoms were positioned geometrically, with C-H = 0.93, 0.97 and 0.96 Å for aromatic, methylene and methyl C-atoms and constrained to ride on their parent atoms. The H-atoms attached to N2 and O3 atoms were located in fourier synthesis and their coordinates were refined. The thermal parameter of H-atoms of methyl group was taken 1.5 times of the parent C-atom, whereas for all other H-atoms it was taken 1.2 times of their parent atoms.

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.
