Methyl 2-amino-5-bromobenzoate
In the title compound, C(8)H(8)BrNO(2), the dihedral angle between the aromatic ring and the methyl acetate side chain is 5.73 (12)°. The mol-ecular conformation is stabilized by an intra-molecular N-H⋯O hydrogen bond, generating an S(6) ring. In the crystal, mol-ecules are connected by N-H⋯O inter-actions, generating zigzag chains running along the b-axis direction.
متن کاملMethyl 2-amino-5-chlorobenzoate
The title compound, C(8)H(8)ClNO(2), is almost planar, with an r.m.s. deviation of 0.0410 Å from the plane through the non-hydrogen atoms. In the crystal structure, inter-molecular N-H⋯O hydrogen bonds link the mol-ecules into chains along the b axis. An intra-molecular N-H⋯O hydrogen bond results in the formation of a six-membered ring.
متن کاملMethyl 4-amino-2-chloropyrimidine-5-carboxylate
In the title compound, C6H6ClN3O2, all non-H atoms are approximately coplanar [maximum deviation = 0.012 (4) Å]; an intra-molecular N-H⋯O hydrogen bond occurs between the amino group and the carbonyl group. In the crystal, mol-ecules are linked by N-H⋯N hydrogen bonds into supra-molecular chains propagated along [101].
متن کامل5-Amino-1,3,4-thiadiazol-2(3H)-one
The asymmetric unit of the title compound, C(2)H(3)N(3)OS, contains three independent mol-ecules which are essentially planar, with r.m.s. deviations of 0.011 (2)-0.027 (2) Å from the mean plane defined by the seven non-H atoms. In the crystal, N-H⋯N and N-H⋯O hydrogen bonds link the mol-ecules into a sheet parallel to the (111) plane.
متن کامل5-Isopropyl-5-methyl-2-sulfanylideneimidazolidin-4-one
In the title compound, C7H12N2OS, the 2-sulfanylideneimidazolidin-4-one moiety is nearly planar, with a maximum deviation of 0.054 (2) Å. In the crystal, a pair of N-H⋯O hydrogen bonds and a pair of N-H⋯S hydrogen bonds each form a centrosymmetric ring with an R 2 (2)(8) graph-set motif. The enanti-omeric R and S mol-ecules are alternately linked into a tape along [1-10] via these pairs of hydr...
