6, (I), contains an intramolecular N-H
O hydrogen bond and a weak C-H
O hydrogen bond, which forms a
C(10) chain motif running parallel to the
c axis. The 6-amino-1,3-benzodioxol-5-yl moieties are involved in
-
stacking. 1-(6-Amino-1,3-benzodioxol-5-yl)-3-[4-(

2O
3, (II), crystallizes with two molecules in the asymmetric unit. The main feature of the supramolecular structure of (II) is the formation of a centrosymmetric hydrogen-bonded tetramer with an
R84(16) motif.

For (I), a mixture of 6'-amino-3',4'-(methylenedioxy)acetophenone (0.50 g, 2.79 mmol), 3,4,5-trimethoxybenzaldehyde (2.79 mmol), ethanol (10 ml) and NaOH (0.5 ml, 20% aq.) was heated to 333–343 K for 10–15 min and the reaction
monitored by thin-layer chromatography. After cooling, the solid formed was
filtered and washed with ethanol to yield pure (I) as orange crystals (93%
yield; m.p. 464 K). For (II), a mixture of
6'-amino-3',4'-(methylenedioxy)acetophenone (0.50 g, 2.79 mmol),
4-(N,N-dimethylamino)benzaldehyde (2.79 mmol), ethanol (10 ml)
and NaOH (0.5 ml, 20% aq.) was heated to 333–343 K for 10–15 min and the
reaction monitored by thin-layer chromatography. After cooling, the solid
formed was filtered and washed with ethanol to yield pure (II) as purple
crystals (46% yield; m.p. 435 K). For both (I) and (II), crystals suitable for
single-crystal X-ray diffraction were selected directly from the prepared
samples.
For both compounds, H atoms were treated as riding, with C—H = 0.95 to 0.99 Å. In the case of the N—H bonds, the H atoms were initially located on a
difference Fourier map. The bond lengths were then DFIXed (SHELXL97;
Sheldrick, 1997) to 0.880 Å with an e.s.d. of 0.005 until a value close to
0.88 Å was obtained, at which stage they were AFIXed (SHELXL97) and
allowed to ride on their parent atoms.
For both compounds, data collection: KappaCCD Server Software (Nonius, 1997); cell refinement: DENZO-SMN (Otwinowski & Minor, 1997); data reduction: DENZO-SMN; program(s) used to solve structure: SHELXS97 (Sheldrick, 1997); program(s) used to refine structure: SHELXL97 (Sheldrick, 1997); molecular graphics: ORTEPII (Johnson, 1976) and PLATON (Spek, 2000); software used to prepare material for publication: SHELXL97 and PRPKAPPA (Ferguson, 1999).

Many synthetic or naturally occurring compounds containing the 1,3-dioxolyl group in their structures are very important because of their pharmacological properties (Ma et al., 1987; Ohta & Kimoto, 1976; Schlunke & Egli, 1972; Krause & Goeber, 1972; Gabrielsen et al., 1992). Chalcones (1,3-diarylpropenones) have been widely used as starting materials in numerous synthetic reactions (Awad et al., 1960; Coudert et al., 1988; Carrie & Rochard, 1963), including the preparation of fused-ring heterocyclic compounds (Insuasty et al., 1992, 1997; Kolos et al., 1996). We have prepared the title compounds, (I) and (II), as intermediates in the synthesis of novel dihydroquinolinones. This is a class of compounds with interesting pharmaceutical properties (Pfizer, 1980; Jordis et al., 1991; Baker et al., 1990), since the 1,3-dioxolyl residue in their frameworks enhances their practical applications. \sch
The molecular structures of (I) and of the two independent molecules of (II) are shown in Figs. 1 and 2, respectively. The dioxol-5-yl groups in all three molecules have C2 envelope puckers. In (I), a strong intramolecular hydrogen bond is observed with an S(6) motif via N5—H5A···O8 (Bernstein et al., 1995) (Fig. 1, Table 1), and likewise in (II) via N15—H15A···O18 and N25—H25A···O28 (Fig. 2, Table 2).
The supramolecular structures of (I) and (II) are completely different. In (I), a C(10) motif is formed via C16—H16···O1(x, -1/2 - y, z - 1/2), creating a chain which runs parallel to the c axis. Two such anti-parallel chains are shown in Fig. 3. Atom H5B is not involved in any hydrogen bonding. In (II), however, the equivalent H atoms H15B and H25B are involved in strong hydrogen bonds via N15—N15B···O28(1 - x, 1 - y, 1 - z) and N25—H25B···O18, linking molecules 1 and 2 to form a tetramer with an R84(16) motif (Fig. 4). Such motifs occur centred at (l + 1/2, m + 1/2, n + 1/2), where l, m and n are integer or zero. The weak C14—H14···O28(1 - x, 1 - y, 1 - z) and C24—H24···O18 hydrogen bonds help to reinforce this tetramer structure. The tetramers are linked to each other by weak hydrogen bonds via C212—H212···O13(x, y, z - 1) and C212(1 - x, 1 - y, z)-H212(1 - x, 1 - y, z)···O13(1 - x, 1 - y, 1 - z), which form bridging R44(26) rings along with the N15—H15···O28 hydrogen bonds of the tetramer (Fig. 5).
In (I), there is π···π stacking between the benzo-1,3-dioxol-5-yl groups, where the rings defined by O1—C2—O3—C3a—C7a and C3a—C4—C5—C6—C7—C7a are stacked such that the distance between the centres of gravity of the rings is 3.7276 (9) Å, the dihedral angle is 3.50°, the perpendicular distance from the centre of gravity of the former ring at (x, y, z) to the latter at (x, 1 + y, z) is 3.368 Å and the perpendicular distance from the centre of gravity of the latter ring at (x, y, z) to the former at (x, y - 1, z) is 3.445 Å (Fig. 6). It is worth noting that the dihedral angle between these planes, 3.50°, is in fact the dihedral angle between the two components of the benzo-1,3-dioxol-5-yl group, which is not in itself planar. There is no π–π stacking in (II).
