Project description:In the title compound, C(13)H(19)ClN(3)O(3) (+)·ClO(4) (-), the 3-(di-meth-yl-ammonio)-propyl group of the cation is disordered over two sets of sites with occupancies 0.772?(6) and 0.228?(6). The cations are joined by pairs of N-H?O hydrogen bonds into centrosymmetric dimers and these dimers are assembled into chains along the a-axis direction, also through N-H?O hydrogen bonds. The perchlorate anions are linked to the hy-droxy groups of the cations by O-H?O hydrogen bonds. The positively charged ammonium groups and the anions give rise to folded layers parallel to the ab plane.

Project description:In the title racemic compound, C(26)H(32)N(2)O(3), an intra-molecular O-H?N hydrogen bond is formed between the phenolic OH group and the tertiary amine N atom.

2-{[(4-{[(2-Hy-droxy-phen-yl)(phen-yl)methyl-idene]amino}-but-yl)imino](phen-yl)meth-yl}phenol.

Project description:The asymmetric unit of the title compound, C(30)H(28)N(2)O(2), comprises half of a potential tetra-dentate Schiff base ligand; an inversion centre is situtated at the center of the butane-diamine spacer. The central methyl-ene segment of the diamine spacer is disordered over two positions with a refined site-occupancy ratio of 0.651 (7):0.349 (7). The phenyl ring and the hy-droxy-substituted benzene ring are almost perpendicular to each other, with a dihedral angle of 87.90 (8) Å. Intra-molecular O-H⋯N hydrogen bonds make S(6) ring motifs.

Bis-{(E)-3-[2-(hy-droxy-imino)-propan-amido]-2,2-dimethyl-propan-1-aminium} bis[?-(E)-N-(3-amino-2,2-dimethyl-prop-yl)-2-(hy-droxy-imino)-propanamido-(2-)]bis-{[(E)-N-(3-amino-2,2-dimethyl-prop-yl)-2-(hy-droxy-imino)-propanamide]-copper(II)} bis-((E)-{3-[2-(hy-droxy-imino)-propanamido]-2,2-dimethyl-prop-yl}carbamate) acetonitrile disolvate.

Project description:The reaction between copper(II) nitrate and (E)-N-(3-amino-2,2-dimethyl-prop-yl)-2-(hy-droxy-imino)-propanamide led to the formation of the dinuclear centrosymmetric copper(II) title complex, (C8H18N3O2)2[Cu2(C8H15N3O2)2(C8H17N3O2)2](C9H16N3O4)2·2CH3CN, in which an inversion center is located at the midpoint of the Cu2 unit in the center of the neutral [Cu2(C8H15N3O2)2(C8H17N3O2)2] complex fragment. The Cu(2+) ions are connected by two N-O bridging groups [Cu?Cu separation = 4.0608?(5)?Å] while the Cu(II) ions are five-coordinated in a square-pyramidal N4O coordination environment. The complex mol-ecule co-crystallizes with two mol-ecules of acetonitrile, two mol-ecules of the protonated ligand (E)-3-[2-(hy-droxy-imino)-propanamido]-2,2-dimethyl-propan-1-aminium and two negatively charged (E)-{3-[2-(hy-droxy-imino)-propanamido]-2,2-dimethyl-prop-yl}carbamate anions, which were probably formed as a result of condensation between (E)-N-(3-amino-2,2-dimethyl-prop-yl)-2-(hy-droxy-imino)-propanamide and hydro-gencarbonate anions. In the crystal, the complex fragment [Cu2(C8H15N3O2)2(C8H17N3O2)2] and the ion pair C8H18N3O2(+.)C9H16N3O4(-) are connected via an extended system of hydrogen bonds.

Project description:The asymmetric unit of the title compound, C(17)H(17)NO(2), contains two crystallographically independent mol-ecules.

The two benzene rings in each of the mol-ecules make dihedral angles of 20.21?(6) and 48.64?(4)°. In the crystal, adjacent mol-ecules are linked by O-H?O hydrogen bonds into infinite polymeric chains.

Project description:The mol-ecule of the title compound, C(17)H(16)O(3), exists in the E conformation with respect to the central C=C bond, is almost planar(r.m.s. deviation = 0.003?Å) and has an intra-molecular O-H?O hydrogen bond, which generates an S(6) ring. In the crystal, mol-ecules are linked by C-H?O inter-actions.
