Acetoguanamine N,N-dimethylformamide solvate
نویسنده
چکیده
The structure of acetoguanamine (or 2,4-diamino-6-methyl-1,3,5-triazine) has been determined as the N,N-dimethyl-formamide solvate, C(4)H(7)N(5)·C(3)H(7)NO. The mol-ecular components are associated in the crystal structure to form ribbons stabilized by three N-H⋯N and one N-H⋯O hydrogen bonds which involve NH groups as donors and the N atoms of the heterocyclic ring and the carbonyl O atom of the solvent as acceptors.

In the title compound, [Cu(C(20)H(10)Br(4)N(2)O(2))(C(3)H(7)NO)]·C(3)H(7)NO, the Cu(II) ion is coordinated by two N atoms and two O atoms from a tetra-dentate Schiff base ligand and the O atom of one dimethyl-formamide ligand in an almost square-pyramidal geometry. The uncoordinated dimethyl-formamide solvent mol-ecule is disordered over two sets of positions with occupancies of 0.741 (4) and 0...

In the title complex, {[HgI(2)(C(17)H(13)N(5)O(2))]·C(3)H(7)NO}(n), the Hg atom is coordinated by two I atoms and two N atoms from two different ligands in a distorted tetra-hedral environment. Hg atoms are bridged by N,N'-di-3-pyridylpyridine-2,6-dicarboxamide ligands, forming a helical chain running along the a axis.

The Schiff base mol-ecule of the title compound, C(15)H(14)N(2)O(4)·C(3)H(7)NO, adopts a trans configuration with respect to the C=N double bond; the Schiff base itself is nearly planar (r.m.s. deviation 0.20 Å). The amido N atom is a hydrogen-bond donor to the dimethyl-formamide solvate mol-ecule. One of the hydr-oxy groups forms an intra-molecular hydrogen bond to the N atom of the C=N double...

In the title compound, C(14)H(9)Cl(2)N(3)O(3)S·C(3)H(7)NO, the two aromatic rings enclose a dihedral angle of 32.93 (12)°. The thiourea mol-ecule exists in its thione form in the solid state with typical C=S and C-N bond lengths. In the crystal, N-H⋯O hydrogen bonds exist between the thio-urea and carbonyl groups on the same and neighboring mol-ecules. In addition, each dimethyl-formamide solva...
