Project description:In the crystal of the title compound, (C(7)H(10)NO)(4)[BiCl(6)]Cl·H(2)O, the Bi(III) cation is located on an inversion center and coordinated by six Cl(-) anions in a slightly distorted octa-hedral geometry; the uncoordinated Cl(-) anion and lattice water mol-ecule are located on a twofold rotation axis. Two independent 4-meth-oxy-anilinium cations are linked to the Bi complex, the uncoordinated Cl(-) anion and lattice water mol-ecule via N-H⋯Cl and N-H⋯O hydrogen bonds.
Project description:The crystal structure of the title compound, C(14)H(15)N(2)O(4) (+)·Cl(-), can be described as being composed of layers containing both cations and anions that are staggered along [010]. Two types of the hydrogen bonds are observed, viz. cation-anion and cation-cation. The chloride anions are acceptors of the strong hydrogen bonds donated by the secondary amine and the hy-droxy groups. The packing is also stabilized by weak C-H⋯O inter-molecular hydrogen bonds. An intra-molecular N-H⋯O inter-action also occurs.
Project description:The title compound, C(8)H(12)NO(+)·Cl(-), consists of an almost planar protonated 4-eth-oxy-anilinium cation with the N atom showing the biggest deviation from the plane formed by all non-H atoms of the cation [0.066 (1) Å]. In the crystal, N-H⋯Cl hydrogen bonds link cations and anions into chains along the a axis. Additional C-H⋯π and π-π inter-actions [centroid-centroid distance = 4.873 (2) Å] stabilize the crystal structure.
Project description:In the title salt, C(7)H(8)NO(2) (+)·Cl(-), the cation and anion are linked by an O-H⋯Cl hydrogen bond. The three-dimensional crystal structure is stabilized by N-H⋯O and N-H⋯Cl hydrogen bonds.
Project description:The crystal structure of the title compound, C(7)H(10)NO(+)·I(-), displays N-H⋯I hydrogen bonds between the 4-meth-oxy-anilinium cations and the iodide anion together with weaker C-H⋯π contacts.
Project description:The title compound, C(7)H(10)NO(+)·NO(3) (-), crystallized with two p-ansidinium cations and two nitrate anions in the asymmetric unit. As well as Columbic and van der Waals forces, moleucles inter-act via multiple bifurcated N-H⋯O hydrogen bonds that help consolidate the crystal packing, resulting in a three-dimensional network.
Project description:In the crystal of the title compound, C(8)H(10)NO(2) (+)·Cl(-), alternating layers of hydro-phobic and hydro-philic zones stack along the c axis. The chloride anions are sandwiched between the 4-(carboxy-meth-yl)anilinium layers, forming inter-molecular O-H⋯Cl and N-H⋯Cl hydrogen bonds with the ammonium and carboxyl groups of the cations. In addition, inter-molecular N-H⋯O and weak C-H⋯O and C-H⋯Cl hydrogen bonds help stabilize the crystal structure.
Project description:In the title hydro-bromide salt, C(8)H(10)NO(3) (+)·Br(-), the positive charge resides on the N atom and the carboxyl -CO(2) end of the cation carries an H atom. In the crystal, N-H⋯Br, O-H⋯Br and N-H⋯O hydrogen bonds link the cations and anions, forming a ladder propagating along the a axis.
Project description:The title compound, (C7H10NO)[SnCl3], is a new compound with non-linear optical (NLO) properties. The structure is pseudocentrosymmetric; the absence of an inversion centre was proved by the Kurtz and Perry method showing a significant second harmonic generation (SHG) signal about ten times lower than that from potassium dihydrogenphosphate. The crystal structure exhibits alternating organic and inorganic layers parallel to the ab plane, which are stabilized by inter-molecular N-H⋯Cl inter-actions.
