5-Chloropyrimidin-2-amine
The complete mol-ecule of the title compound, C(4)H(3)ClN(3), is generated by crystallographic mirror symmetry, with the Cl atom, one N atom and two C atoms lying on the reflecting plane. In the crystal structure, inter-molecular N-H⋯N hydrogen bonds link the mol-ecules into chains propagating in [100].
متن کامل5-Iodopyrimidin-2-amine
The mol-ecule of the title compound, C(4)H(4)IN(3), has crystallographic mirror plane symmetry. In the crystal, the mol-ecules are connected through N-H⋯N hydrogen bonds into polymeric tapes extended along the a axis, which are typical of 2-amino-pyrimidines. Each mol-ecule acts as a double donor and a double acceptor in the hydrogen bonding.

The asymmetric unit of the title compound, C(9)H(9)N(3)S, contains two crystallographically independent mol-ecules, in which the thia-diazole and tolyl rings are oriented at dihedral angles of 32.25 (3) and 74.50 (3)°. An intra-molecular C-H⋯S inter-action results in the formation of a five-membered ring. In the crystal structure, inter-molecular N-H⋯N hydrogen bonds link the mol-ecules into ch...

The title compound, C(14)H(11)N(3)OS, was synthesized by the reaction of phenoxy-benzoic acid and thio-semicarbazide. The thia-diazole ring makes dihedral angles of 0.99 (16) and 86.53 (18)°, respectively, with the benzene and phenyl rings. The dihedral angle between the benzene and phenyl rings is 87.17 (19)°. Intra-molecular C-H⋯S contacts are present. In the crystal, inter-molecular N-H⋯N hy...
