In the structure of the title compound, C22H22N4O4·C3H7NO·H2O, the entire tricyclic system is approximately planar except for the carbon atom bearing the two methyl groups; the methoxyphenyl ring is approximately perpendicular to the tricycle. All seven potential hydrogen-bond donors take part in classical hydrogen bonds. The main molecule and the DMF combine to form broad ribbons parallel to the a axis and roughly parallel to the ab plane; the water molecules connect the residues in the third dimension.
Keywords: crystal structure; chromenopyridine; solvate; secondary interactions.

1. Chemical context
Activated α,β-unsaturated nitrile moieties are involved in a wide variety of natural plant products, drugs, colourants and agrochemicals (Fleming & Wang, 2003; Ahmed et al., 2022); they also represent versatile starting materials for the synthesis of a wide variety of therapeutically important heterocycles (Zhang et al., 2019; Metwally et al., 2023). The generally accepted importance of these functions (Wang et al., 2016; Hebishy et al., 2023) is reflected in the investment of much effort to synthesize them (Zhang et al., 2023; Elgemeie et al., 1998a,b). Recently, we have reported several new methods for the synthesis of pharmaceutically relevant heterocycles utilizing activated and α,β-unsaturated as starting materials (e.g. Mohamed-Ezzat et al., 2021). In this context, we and others have synthesized several condensed carbocyclic pyrans and carbocyclic pyridines using dimedone as the starting material (Hebishy et al., 2022; Tu et al., 2014).
andThe present investigation reports a new one-pot synthesis of condensed carbocyclic pyridines by the reaction of dimedone with enamino 1) reacted with 4-hydroxy-3-methoxybenzaldehyde (2) and dimedone (4) in refluxing n-butanol containing catalytic amounts of trimethylamine to give the corresponding condensed chromeno[2,3-b]pyridine-3-carbonitrile (7) (Fig. 1). The structure of 7 was confirmed on the basis of elemental analysis and spectroscopic studies (1H NMR, IR and MS). We suggest that the formation mechanism of 7 from 1, 2 and 4 involves a condensation reaction that consists of an initial Michael addition of the methylene group of the dimedone 4 to the double bond of intermediate 3 to give the next intermediate 5, which then cyclizes to the condensed chromeno[2,3-b]pyridine-3-carbonitrile 7. In order to establish the structure of the compound unambiguously, the was determined and is presented here.
It was found that 2-aminoprop-1-ene-1,1,3-tricarbonitrile (2. Structural commentary
The structure of the product 7, which crystallized from DMF as a 1/1/1 adduct with DMF and water, is shown in Fig. 2. Molecular dimensions, a selection of which are given in Table 1, may be regarded as normal (e.g. the double-bond length C5A=C9A). The pyridinic ring is planar, and its direct substituents also lie in the same plane (r.m.s. deviation of eleven atoms = 0.008 Å); the angle between this plane and that of the methoxyphenyl ring is 77.86 (2)°. The atoms C5A and C9A lie 0.317 (1) and 0.249 (1) Å, respectively, out of the plane in the same direction. The central ring has the form of a flattened boat, with C5 and O10 lying 0.166 (1) and 0.101 (1) Å, respectively, out of the plane of the other four atoms (r.m.s. deviation = 0.015 Å). The third ring of the tricyclic system, formally related to cyclohexen-2-one, has the expected envelope form, in which the atom C8 lies 0.673 (1) Å out of the plane of the other five atoms (r.m.s. deviation 0.029 Å). Viewed from the side (Fig. 3), it can be seen that the entire tricyclic system is approximately planar (r.m.s. deviation 0.14 Å) except for C8.

3. Supramolecular features
All seven of the potential hydrogen-bond donors do indeed take part in classical hydrogen bonds (Table 2), although the contact N4—H03⋯O98 is appreciably longer than the others, and O99—H07 is part of a three-centre system with N1 and the more distant O10 as acceptors. There is also one short linear contact involving a phenyl hydrogen, C22—H22⋯O98, which may be considered as a weak hydrogen bond; this is, however, not represented in the Figures for clarity reasons.
The molecules of 7 and the DMF combine to form broad ribbons parallel to the a axis (Fig. 4), in which inversion-symmetric R22(12) rings, based on the hydrogen bond N4—H04⋯N3, are prominent. The DMF molecules project above and below the planes of the ribbons. The water molecules connect the residues in the third dimension (Fig. 5). They accept one hydrogen bond and act as donor for three hydrogen bonds (counting both branches of the three-centre system).
4. Database survey
The search employed the routine ConQuest (Bruno et al., 2002), part of Version 2022.3.0 of the Cambridge Database (Groom et al., 2016).
A search for the same tricyclic ring system gave only one hit, namely 8-(furan-2-yl)-12-(4-methoxyphenyl)-3,3,11-trimethyl-3,4,7,8,9,12-hexahydro-1H-chromeno[2,3-b]quinoline-1,10(2H)-dione (refcode EVANEW; Han et al., 2015). This, however, has a further cyclohexanone-type ring fused to the pyridinic ring. In common with compound 7, it bears two methyl groups at the atom corresponding to our C8, a keto function at C6 and an aromatic substituent (p-methoxyphenyl) at C5. The interplanar angle involving this ring is given as 83.7 (7)°.
A search for solvates with precisely one DMF and one water molecule (under the stringent conditions only organic, no disorder, no ionic compounds, no metals, all solvent H present) gave only 32 hits. We did not check for the plausibility of the water H atoms. The structures represented a broad distribution of organic compounds, e.g. during systematic studies of solvates of [17,23-dibromo-18,22-dinitro-2,5,8,11,14-pentaoxa-26-azatetracyclo-(13.9.3.019,27.021,25)heptacosa-1(24),15,17,19 (27),21 (25),22-hexaene-20(26H)-one, refcode AMARAH; Huszthy et al., 2003] or [bis(17β-hydroxy-17α-methylandrostano[3,2-c]pyrazole, AVEQUO; Karpinska et al., 2011]. Heterocyclic systems with groups likely to hydrogen bond were also well represented, e.g. 2′-amino-6′-ethyl-2,5′-dioxo-1,2,5′,6′-tetrahydrospiro[indole-3,4′-pyrano[3,2-c]quinoline]-3′-carbonitrile (MESVAL; Upadhyay et al., 2023). Our own studies have shown that DMF is often a useful solvent for crystallization of as a hydrogen-bond acceptor, it has formed solvates with N-[2-amino-5-cyano-4-(methylsulfanyl)-6-oxopyrimidin-1(6H)-yl]-4-bromobenzenesulfonamide (WUSMUU; Elgemeie et al., 2015) and N-[6-amino-5-(1,3-benzothiazol-2-yl)-3-cyano-4-(methylsulfanyl)-2-oxopyridin-1(2H)-yl]-4-methylbenzene-1-sulfonamide (ZELBUQ; Azzam et al., 2017).

6. Refinement
Crystal data, data collection and structure . Hydrogen atoms bonded to nitrogen or oxygen were refined freely. The methyl groups were included as an idealized rigid group allowed to rotate but not tip (command AFIX 137), with C—H = 0.99 Å and H—C—H = 109.5°. Other hydrogen atoms were included using a riding model starting from calculated positions (C—Hmethylene = 0.99, C—Hmethine = 1.00, C—Harom = 0.95 Å). The U(H) values were fixed at 1.5 × Ueq of the parent carbon atoms for the methyl groups and 1.2 × Ueq for other hydrogens. Three reflections, with intensities clearly in error, were omitted. The largest peaks of residual electron density (max. 0.67 e Å−3) lie in the middle of bonds and thus do not give cause for concern.
