4-Acetyl-3-(p-anis-yl)sydnone.

ABSTRACT: THE ASYMMETRIC UNIT OF THE TITLE COMPOUND [SYSTEMATIC NAME: 4-acetyl-3-(4-meth-oxy-phen-yl)-1,2,3-oxadiazol-3-ium-5-olate], C(11)H(10)N(2)O(4), contains four crystallographically independent mol-ecules. The 1,2,3-oxadiazole rings are almost planar [maximum deviations = 0.006?(3), 0.006?(3), 0.002?(3) and 0.009?(3)?Å] and form dihedral angles of 55.03?(14), 61.02?(13), 58.36?(14) and 53.79?(15)° with their attached benzene rings. In the crystal, inter-molecular C-H?O and C-H?N hydrogen bonds link the mol-ecules, forming sheets parallel to (011).

3-(2-Acetamido-phen-yl)sydnone.

Project description:Sydnones are unusual mesoionic compounds containing a five-membered heterocyclic ring. Generally for stability, substitution at the N-3 position by an aromatic fragment is necessary. In the title compound, C(10)H(9)N(3)O(3), the aromatic substitutent is 2-acetamido-phenyl. The two planar ring fragments are twisted relative to one another, with a inter-planar angle of 63.13?(5)°. The mol-ecules are packed into the unit cell via ?-? inter-actions between the phenyl rings [inter-planar separation = 3.4182?(4)?Å] and between the sydnone rings [inter-planar separation = 3.2095?(4)?Å]. N-H?O and C-H?O hydrogen bonding is also found inter-nally and externally to the mol-ecule.

Crystal structure of 4-(2-bromo-prop-ion-yl)-3-phenyl-sydnone.

Project description:Sydnones are a class of mesoionic compounds containing a five-membered heterocyclic ring. In general, sydnone com-pounds are synthesized with an aromatic substutuent at the N(3) position. This feature, adds to the stability of the heterocyclic ring. In the title compound {systematic name: 4-(2-bromo-propano-yl)-3-phenyl-1,2,3?(5)-oxa-diazol-3-ylium-5-olate}, C11H9BrN2O3, the aromatic substitutent is an unsubstituted phenyl ring. The sydnone ring is almost planar, with a maximum deviation from the mean plane of 0.023?(1)?Å, but is not coplanar with the phenyl ring, having a dihedral angle of 40.93?(8)°. The carbonyl side chain is twisted relative to the syndone ring by 15.8?(2)°. The mol-ecules are packed in the unit cell as pairs related by an inversion center at (1, 0, 1/2). The pairs inter-act via ?-stacking, with the distance separating the centroids being 3.824?(1)?Å. The Br atom has two contacts, one to an N atom in a neighboring asymmetric unit with a distance of 3.346?(2)?Å (the sum of the van der Waals radii is 3.40?Å) and a second to an H atom with a distance of 3.03?Å. The contact with the H atom is perpendicular (C-Br?H = 98.60°) to the C-Br bond, and that to the N atom is linear [C-Br?N = 169.10?(5)°] to the C-Br bond. The O atom of the sydnone ring is involved in two hydrogen bonds, one intra-molecular with a donor-acceptor distance of 3.1486?(19)?Å and a second that is inter-molecular, with a phenyl H atom as the donor and has a donor-acceptor distance of 3.346?(2)?Å.

In the crystal structure, inter-molecular C-H?O and C-H?N hydrogen bonds link neighbouring mol-ecules into two-mol-ecule-thick arrays parallel to the bc plane. A short S?O inter-action [2.9565?(19)?Å] also occurs.
