2-[(2-{Bis[2-(2-hydroxy-5-nitrobenzylideneamino)ethyl]amino}ethyl)iminomethyl]-4-nitrophenol acetonitrile monosolvate
In the title compound, C(27)H(27)N(7)O(9)·CH(3)CN, the three nitro groups of the polydentate tripodal Schiff base are located approximately parallel to their respective carrier benzene rings, making dihedral angles of 3.9 (4), 5.0 (4) and 6.3 (4)°. Intra-molecular O-H⋯N hydrogen bonds between the hy-droxy O atoms and the imine N atoms, with O⋯N distances in the range 2.607 (3)-2.665 (3) Å, form...

The structure of the title salt, (C5H6BrN2)[ZnCl3(C5H5BrN2)], consists of discrete 2-amino-5-bromo-pyridin-1-ium cations and distorted tetra-hedral (2-amino-5-bromo-pyridine)-tri-chlorido-zincate anions. In the crystal, the complex anions and cations are linked via N-H⋯Cl hydrogen bonds into layers parallel to (101). Short Br⋯Cl contacts of 3.4239 (11) and 3.4503 (12) Å are observed, as well as...
متن کامل1-(5-Bromo-2-oxoindolin-3-ylidene)thiosemicarbazide acetonitrile monosolvate
In the crystal structure of the title compound, C(9)H(7)BrN(4)OS·C(2)H(3)N, the mol-ecules are connected via N-H⋯O and N-H⋯S inter-actions into zigzag chains perpendicular to [001]. The mol-ecules in these chains are additionally linked to acetonitrile solvent mol-ecules through N-H⋯N hydrogen bonding. The mol-ecules are arranged in layers and are stacked in the direction of the c axis indicati...

In the title compound, C(9)H(11)N(3)O·CH(4)O, the semicarbazone moiety is nearly planar [maximum deviation = 0.017 (2) Å] and is twisted by a dihedral angle of 29.40 (13)° with respect to the phenyl ring. The semicarbazone moiety and phenyl ring are located on opposite sides of the C=N bond, showing the E configuration. An inter-molecular O-H⋯O and N-H⋯O hydrogen-bonding network occurs in the c...

In the title compound, C(16)H(13)ClN(2)O(2)·C(2)H(6)O, the fused cyclo-hexene and pyran rings adopt envelope and flattened boat conformations, respectively. In the crystal, N-H⋯O and O-H⋯O hydrogen bonds link the chromene and ethanol solvent mol-ecules into infinite chains along the c axis, and N-H⋯N hydrogen bonds link these chains into a three-dimensional framework. Weak C-H⋯π inter-actions a...
