2-Methyl-sulfonyl-1,2,4-triazolo[1,5-a]quinazolin-5(4H)-one.

ABSTRACT: The triazoloquinazoline fused-ring system of the title compound, C(10)H(8)N(4)O(3)S, is essentially planar (r.m.s. deviation = 0.027?Å). In the crystal, adjacent mol-ecules are linked by N-H?O(sulfon-yl) hydrogen bonds, generating a helical chain running along the b axis.

Project description:The non-H atoms of the title compound, C(10)H(8)N(4)OS, lie approximately in a common plane (r.m.s. deviation = 0.058?Å). In the crystal, two mol-ecules are linked across a center of inversion by a pair of N-H?N hydrogen bonds, forming a a dimer.

2-Benz-yloxy-1,2,4-triazolo[1,5-a]quinazolin-5(4H)-one.

Project description:The title compound, C(16)H(12)N(4)O(2), is a functionalized triazoloquinazoline with a substituted benz-yloxy group attached at the 2-position of a triazole spacer. The triazoloquinazoline fused-ring system is approximately planar (r.m.s. deviation = 0.016 Å) while the benzyl substituent is perpendicular to the ring system, making a dihedral angle of 65.29 (6)°. The phenyl ring of the benz-yloxy moiety is equally disordered over two sets of sites. A centrosymmetric N-H⋯N hydrogen bond connects mol-ecules into dimers.

2-Methyl-sulfanyl-1,2,4-triazolo[1,5-a]quinazoline-5(4H)-thione.

Project description:In the title compound, C10H8N4S2, comprising fused six-, six- and five-membered rings, the mol-ecule is close to being planar (r.m.s. deviation of the non-H atoms = 0.041?Å). The S-bound methyl group is folded away from the single N atom of the triazole ring and the NH group of the six-membered ring, allowing for the formation of centrosymmetric eight-membered {?HNCN}2 synthons in the crystal. The resulting inversion dimers are connected into supra-molecular stacks aligned along the b-axis direction by ?-? inter-actions [centroid-centroid distances = 3.6531?(12) and 3.7182?(12)?Å].

2-Phenyl-7-(4-pyridyl-methyl-amino)-1,2,4-triazolo[1,5-a][1,3,5]triazin-5(4H)-one.

Project description:In the title compound, C(16)H(13)N(7)O, the 1,2,4-triazolo[1,5-a][1,3,5]triazine heterocyclic system is essentially planar (r.m.s. deviation = 0.0375?Å). The attached benzene ring lies almost in the mean plane of 1,2,4-triazolo[1,5-a][1,3,5]triazine [dihedral angle = 1.36?(23)°], while the pyridine ring is turned out of this plane by the amino-methyl bridge [dihedral angle = 69.22?(9)°]. The amino group H atom is involved in intra-molecular hydrogen bonding with a triazole N atom. In the crystal, mol-ecules are connected via C(=O)NH?N hydrogen bonds into C(11) chains parallel to [100]. The amino group H atom acts as a hydrogen-bond donor, forming an NH?O=C hydrogen bond with the carbonyl O atom, which links the mol-ecules into C(6) chains running along [011] and [01].

Project description:The triazoloquinazole fused-ring system of the title compound, C(10)H(7)ClN(4)O(2)S, is essentially planar (r.m.s. deviation = 0.009?Å).

4,7-Phenanthrolinium perchlorate-5-methyl-1,2,4-triazolo[1,5-a]pyrimidin-7(4H)-one-water (1/1/2).

Project description:The asymmetric unit of the title compound, C(12)H(9)N(2) (+)·ClO(4) (-)·C(6)H(6)N(4)O·2H(2)O, contains a monoprotonated 4,7-phenanthrolinium (47phen) cation, a perchlorate anion balancing its charge, a neutral mol-ecule of 5-methyl-1,2,4-triazolo[1,5-a]pyrimidin-7(4H)-one (HmtpO) and two inter-stitial water mol-ecules. In the crystal structure, the acidic H atoms of 47phenH(+) and HmtpO form strong hydrogen bonds with the water mol-ecules, which in turn act as hydrogen-bond donors, forming links between them and towards the carbonyl O atom of HmtpO, the non-protonated N atom of 47phen(+) and one of the O atoms of the anion.

Project description:In the title mol-ecule, C14H10N6O, the planes of the methyl-furazan fragment and the phenyl ring attached to the triazolo-pyrimidine bicycle are twisted from the mean plane of the bicycle at angles of 45.92?(5) and 5.45?(4)°, respectively. In the crystal, ?-? inter-actions, indicated by short distances [in the range 3.456?(3)-3.591?(3)?Å] between the centroids of the five- and six-membered rings of neighbouring mol-ecules, link the mol-ecules into stacks propagating along the c-axis direction.
