The title compound, C17H12N4O3, a pyrido-pyrrolo-pyrimidine derivative, is almost planar. The nitro-benzene ring is inclined to the mean plane of the 8,9-di-hydro-pyrido[2,3-d]pyrrolo-[1,2-a]pyrimidin-5(7H)-one moiety (r.m.s. deviation = 0.023 Å) by 6.8 (1)°. In the crystal, mol-ecules are linked via C-H⋯O and C-H⋯N hydrogen bonds, forming layers parallel(More)
The reaction of 2-(2-oxo-2,3-di-hydro-1,3-benzo-thia-zol-3-yl)acetic acid (NBTA) and tri-ethano-lamine (TEA) with Cd(CH3OO)2 resulted in the formation of the title salt, [Cd(C6H15NO3)2](C9H6NO3S)2. In its crystal structure, the complex cation [Cd(TEA)2](2+) and two independent NBTA(-) units with essentially similar geometries and conformations are present.(More)
Reaction of m-amino-benzoic acid (MABA), di-ethano-lamine (DEA) and MnCl2·4H2O led to the formation of the title salt, [Mn(C4H11NO2)2](C7H6NO2)2. In the complex cation, the Mn(2+) ion is located on an inversion centre and is coordinated by two symmetry-related tridentate DEA mol-ecules, leading to the formation of a slightly distorted MnN2O4 octa-hedron.(More)
The reaction of 2-(2-oxo-2,3-di-hydro-1,3-benzo-thia-zol-3-yl)acetic acid (NBTA) and tri-ethano-lamine (TEA) with Co(NO3)2 results in the formation of the title complex, [Co(C6H15NO3)2](C9H6NO3S)2, which is formed as a result of the association of bis-(tri-ethano-lamine)-cobalt(II) and 2-(2-oxo-2,3-di-hydro-1,3-benzo-thia-zol-3-yl)acetate units.

In the title salt, C2H10N2 (2+)·2C14H10NO3 (-), the ethyl-ene-diaminium dication lies on an inversion centre. In the anion, the benzene rings make a dihedral angle of 33.87 (9)° and intramolecular N-H⋯O and C-H⋯O hydrogen bonds occur. All the amino H atoms are involved in N-H⋯O hydrogen bonds. These hydrogen bonds link the ionic units into a(More)
The title compound, C19H20N2O·C2H5OH, is an ethanol solvate of an indol alkaloid which was extracted from the plant Vinca erecta. The fused piperidine ring adopts an approximate boat conformation and the pyrrolidine ring an envelope conformation with one of the methyl-ene C atoms at the flap. An intra-molecular N-H⋯O hydrogen bond forms an S6 ring motif. In(More)
In the title compound, C(14)H(16)N(6)O(6)·C(2)H(6)O·H(2)O, both substit-uents of the benzene ring are approximately planar with maximum deviations from the mean plane of 0.0561 (12) (an imine N atom) and 0.1419 (11) Å (a meth-oxy O atom). The substituents are tilted out of the plane of the benzene ring by 64.48 (4) and 70.08 (5)°, respectively. In the(More)
In the crystal structure of the title compound, C(6)H(7)N·CH(4)N(2)O, the 2-methyl-pyridine and urea mol-ecules are linked via N-H⋯O and N-H⋯N hydrogen bonds, forming ribbons extending along the a axis. The dihedral angle between the 2-methyl-pyridine and urea mean planes is 89.09 (9)°. The methyl group shows rotational disorder wherein the H atoms are(More)
In the title compound, [Ni(C8H6ClO3)2(H2O)4], the Ni(II) ion is located on a crystallographic inversion centre and is octa-hedrally coordinated by two 2-(4-chloro-phen-oxy)acetate ligands in axial positions and by four water mol-ecules in the equatorial plane. The acetate ligands are bound to the Ni(II) ion in a monodentate manner through a carboxyl-ate O(More)
A new polymorph of 2-(benzotriazol-2-yl)acetic acid, C(8)H(7)N(3)O(2), crystallizes in the space group C2/c (Z = 8). The non-planar mol-ecule has a synplanar conformation of the carb-oxy group. The crystal structure features helices parallel to the b axis sustained by O-H⋯N hydrogen bonding which are similar to those in the known polymorph [Giordano &(More)
