Molecules of the title compound, C10H10N2O5, are linked by
a combination of OÐHÁ Á ÁO and NÐHÁ Á ÁO hydrogen
bonds into (100) sheets containing alternating R22(8) and
R66(36) rings.
is directly linked to four other dimers via the amidic C(4)
chains along [001], so forming a (100) sheet in which centro-
symmetric R22(8) and R66(36) rings alternate in a chessboard
fashion (Fig. 3).
Comment
The reaction of C-substituted anilines, such as nitroanilines,
with succinic anhydride yields initially 3-(arylaminocarbon-
yl)propionic acids, (A) (see scheme), dehydration of which
yields the corresponding N-arylsuccinimides, (B). We have
recently reported the molecular and supramolecular struc-
tures of the three isomeric N-(nitrophenyl)succinimides (B),
where R = NO2 (Glidewell et al., 2005). We have now prepared
all three isomeric 3-(nitrophenylaminocarbonyl)propionic
acids (A), where R = NO2, but unfortunately only the 3-nitro
isomer has provided crystals suitable for single-crystal struc-
ture determination. We report here the molecular and
supramolecular structures of 3-(3-nitrophenylaminocarbon-
yl)propionic acid, (I).
The molecules of (I) (Fig. 1) are linked into sheets by a
combination of an NÐHÁ Á ÁO C hydrogen bond, forming the
usual amidic C(4) chain, and an OÐHÁ Á ÁO hydrogen bond,
forming the usual centrosymmetric R22(8) (Bernstein et al.,
1995) motif characteristic of simple carboxylic acids (Table 1).
Carboxyl atom O43 in the molecule at (x, y, z) acts as a
hydrogen-bond donor to atom O44 in the molecule at (1 x,

(12, 12, 12 ) (Fig. 2). Amide atoms N1 at (x, y, z) and (1 x, 1 y,
z), which form part of the dimer centred at (12, 21, 21 ), act as
