[2,6-Bis(dimethyl-amino-meth-yl)phen-yl]selenium bromide monohydrate.

ABSTRACT: In the title hydrated molecular salt, C(12)H(19)N(2)Se(+)·Br(-)·H(2)O, the two independent bromide anions lie on a twofold rotation axis. Strong intra-molecular N→Se inter-actions [2.185 (3) and 2.181 (3) Å] are established by both N atoms of the organic group in the cation, in trans positions to each other, with an N-Se-N angle of 161.6 (1)°, resulting in a T-shaped (C,N,N')Se core. In the crystal, dimeric associations are formed by Br⋯Se [3.662 (2) Å] and Br⋯H inter-actions [2.56 (6) and 2.63 (7) Å] involving two bromide anions, two cations and two water mol-ecules.

{2-[(Dimethyl-amino)-meth-yl]phen-yl}bis-(4-methyl-phen-yl)bis-muthane.

Project description:The title compound, [Bi(C(7)H(7))(2)(C(9)H(12)N)], was obtained by treating chlorodi(p-tol-yl)bis-muthane with o-lithio-N,N-dimethyl-benzyl-amine. An intra-molecular Bi?N nonbonding inter-action is observed in the distorted trigonal triaryl-bis-muth coordination of the title compound.

Bis{2,6-bis-[(2-hy-droxy-5-methyl-phen-yl)imino-meth-yl]pyridine} monohydrate.

Project description:The title compound, 2C(21)H(19)N(3)O(2)·H(2)O, was synthesized by a Schiff base condensation of 2,6-diformyl-pyridine with 2-amino-4-methyl-phenol in ethanol. In the crystal, two mol-ecules of 2,6-bis-[(2-hy-droxy-5-methyl-phen-yl)imino-meth-yl]pyridine dimer-ize via hydrogen bonding to a water mol-ecule, which lies on a twofold axis. There are also intra-molecular phenol-imine hydrogen bonds. The dimers are further linked via π-π (phen-yl-pyridine) [centroid-centroid distance = 3.707 (2) Å] and π-π edge-to-edge [3.392 (2) Å] inter-actions. The dihedral angles between the central ring and the two pendant rings are 11.46 (8) and 2.06 (8)° while the pendant rings make a dihedral angle of 10.14 (8)°.

[N-((E)-2-{[2-(Dimethyl-amino)-eth-yl]imino-meth-yl}phen-yl)-N-(2,6-dimethyl-phen-yl)anilinido-κN,N',N'']ethyl-zinc.

Project description:The title eth-yl-zinc complex, [Zn(C(2)H(5))(C(19)H(24)N(3))], bears a tridentate anilinide-aldimine ligand and features one long Zn-N(amine) bond length, attributable to the crowded environment of the coordinated metal, arising from the dimethyl-phenyl group. The Zn(II) ion adopts a distorted tetra-hedral geometry, the dihedral angle between the two benzene rings being 86.05 (16)°.

Bis{2-[2-(dimethyl-amino)ethyl-imino-meth-yl]-4,6-disulfanylphenolato}cobalt(II) monohydrate.

Project description:In the title hydrated complex, [Co(C(11)H(15)N(2)OS(2))(2)]·H(2)O, the Co(II) atom (site symmetry 2) is coordinated by two O,N,N'-tridentate Schiff base ligands, resulting in a very distorted cis-CoO(2)N(4) octa-hedral geometry for the metal ion. In the crystal, the water mol-ecule (O-atom site symmetry 2) inter-acts with nearby complex mol-ecules by way of bifurcated O-H?(O,S) hydrogen bonds.

2,6-Bis(4-meth-oxy-phen-yl)-1,3-dimethyl-piperidin-4-one O-benzyl-oxime.

Project description:The central ring of the title compound, C(28)H(32)N(2)O(3), exists in a chair conformation with an equatorial disposition of all the alkyl and aryl groups on the heterocycle. The para-anisyl groups on both sides of the secondary amino group are oriented at an angle of 54.75?(4)° with respect to each other. The oxime derivative exists as an E isomer with the methyl substitution on one of the active methyl-ene centers of the mol-ecule. The crystal packing features weak C-H?O inter-actions.

Tris{2-[(2,6-dimethyl-phen-yl)amino]-eth-yl}amine.

Project description:The title compound, C(30)H(42)N(4), is an aryl-ated tris-(amino-eth-yl)amine derivative which was obtained by reducing the corresponding tris-amide with AlH(3). The asymmetric unit consists of one third of a C(3v)-symmetric mol-ecule with the tertiary N atom lying on a crystallographic threefold axis.

2,6-Bis(4-meth-oxy-phen-yl)-1,4-dithiine.

Project description:The title mol-ecule, C18H16O2S2, reveals crystallographic twofold rotation symmetry (with both S atoms lying on the axis) and one half-mol-ecule defines an asymmetric unit. The dithiine ring is in a boat conformation. The aromatic ring and the C=C bond are nearly coplanar, with small torsion angles of -171.26 (19) and 8.5 (3)°. The two S-C bond lengths [1.7391 (19) and 1.7795 (18) Å] are shorter than single C-S bonds and longer than analogous C=S double bonds, which indicates a certain degree of conjugation between the lone pair on the S atom and π electrons of the C=C bond. The crystal packing only features van der Waals inter-actions.

Project description:In the title compound, C(19)H(19)NO, the dihedral angle between the naphthyl ring system and the phenyl ring is 79.83?(6)°. An intra-molecular O-H?N hydrogen bond, together with van der Waals inter-actions, stabilizes the mol-ecular conformation.
