متن کامل4-Amino-3-bromobenzoic acid
The asymmetric unit of the title compound, C(7)H(6)BrNO(2), consists of two mol-ecules having a small variation of bond lengths and angles. The title compound forms dimers through pairs of O-H⋯O hydrogen bonds involving the carboxyl-ate groups. The dimers are linked into polymeric forms through inter-molecular hydrogen bonds, forming R(2) (1)(6), R(3) (2)(8) and R(3) (3)(15) ring motifs.

In the title ammonium carboxyl-ate-carb-oxy-lic acid co-cystal, C(10)H(9)N(2) (+)·C(8)H(3)I(3)NO(4) (-.)C(8)H(4)I(3)NO(4), the carboxyl-ate anion and carb-oxy-lic acid mol-ecule are linked by O-H⋯O and N-H⋯O hydrogen bonds to form a chain running along the c axis of the monoclinic unit cell. The chains are linked by pyridinum and pyridine N-H⋯O hydrogen bonds, generating a layer motif. O-H⋯N an...

The title compound, C(13)H(18)N(2)O(3), is an inter-mediate in the synthesis of compounds with medicinial applications. The crystal structure is stabilized by inter-molecular N-H⋯O, C-H⋯N and C-H⋯O hydrogen bonds.
متن کامل5-Amino-3-(4-pyridyl)isoxazole
In the title compound, C(8)H(7)N(3)O, there are two independent mol-ecules in the asymmetric unit, in which the angles between the pyridine ring and the isoxazole ring are 35.8 (6) and 10.6 (2)°. The crystal packing is stabilized by N-H⋯N hydrogen bonds, which result in the mol-ecules forming a two-dimensional supra-molecular layer.
