1 Source of materials

A 50 mL ethanol solution of 2.17 g 2-aminophenylarsonic acid (1.0 mmol) and 1.52 g o-vanillin (1.0 mmol) was stirred at 333.15 K for 2 h using 3 drops of concentrated hydrochloric acid as a catalyst, then yellow precipitates were filtered out and dried under the vacuum. The title compound was purified by the recrystallization from the ethanol solution. Yellow crystals suitable for single X-ray diffraction measurement were obtained from the filtrate under slow evaporation in air. Yield: 78.6 % (based on 2-aminophenylarsonic acid).

2 Experimental details

The structure was solved by Direct Methods with the SHELXS-2018 program. All H-atoms from C were positioned with idealized geometry and refined isotropically (U iso(H) = 1.2 U eq(C)) using a riding model with C–H = 0.950 (for benzene ring) and 0.980 Å (for methyl). The H-atoms from O atoms were positioned with idealized geometry (if they were positioned with Q peaks, unreasonable O–H bond lengths were reported) and refined isotropically with U iso(H) = 1.5 U eq(O) and O–H = 0.840 Å.

3 Comment

To date, some single crystal structures of 2-aminophenylarsonic acid, 5 its salts, 6 and its 2-amino-modified derivatives have been reported. 7 , 8 , 9 , 10 , 11 Furthermore, some of them were used as organic components to build zinc, cobalt, cadium, and copper, etc. complexes 12 , 13 , 14 , 15 , 16 , 17 and polyoxometalates, including polyoxovandates, 18 polyoxomolybdates, 19 , 20 and polyoxotungstates. 21 , 22 A convenient way to modify 2-amino group is through Schiff base reaction because there are a large number of aromatic aldehydes to choose. In 2015, Percino and co-workers reported the synthesis and crystal structures reacting 2-amonophenylarsonic acid with equimolar salicylaldehyde in ethanol solution in the presence of HCl as a catalyst. 23 In 2019, they reported three (E)-(2-(substituted benzylidene)aminophenyl)arsonic acids. 24

As shown in the figure, the asymmetrical unit consists of one whole (E)-(2-(2-hydroxy-3-methoxybenzylidene)aminophenyl)arsonic acid. The four bond lengths of As–C and As–O are 1.895, 1.663, 1.699 and 1.700 Å, respectively, which are similar to the reported results. 23 , 24 The o-vanillin residue is almost coplanar that is favor to the strong intramolecular O–H···N interaction (D···Adistance 2.679 Å) 25 between the N1 atom and the substituted –OH group in ortho position of benzene ring, which is distinguished from the rotation or planarity of the molecules due to the intermolecular hydrogen bonds (O1–H1···O3 and O2–H2A···O3) of the 2-aminophenylarsonic acid residue. The two kinds of hydrogen bonds mentioned above (right part of the figure, green dashed lines) are linked to generate a 1D chain-like structure.
