Bis[2,6-bis-(2-meth-oxy-phen-yl)pyridinium] di-μ-bromido-bis-[dibromidocuprate(II)].

ABSTRACT: The title salt, (C(19)H(18)NO(2))(2)[Cu(2)Br(6)], was obtained from an attempt to synthesize the copper(II) complex of 2,6-bis-(2-meth-oxy-phen-yl)pyridine (L) from a reaction between CuBr(2) and one equivalent of L in CH(2)Cl(2) at room temperature. The resulting compound is the salt of the 2,6-bis-(2-meth-oxy-phen-yl)pyridinium cation and 0.5 equivalents of a hexa-bromido-dicuprate(II) dianion. Both meth-oxy groups of the cationic pyridinium moiety are directed towards the N atom of the pyridine ring as a result of intra-molecular N-H⋯O hydrogen bonds. The centrosymmetric hexabromidodicuprate dianion possesses a distorted tetra-hedral geometry at the copper ion. The Cu-Br bond lengths are 2.3385 (7) and 2.3304 (7) Å for the terminal bromides, whereas the bond length between the Cu atom and two bridging bromides is slightly longer [2.4451 (6) Å].

Di-tert-butyl N-[2,6-bis-(methoxy-meth-oxy)phen-yl]imino-diacetate.

Project description:The title mol-ecule, C(20)H(31)NO(8), has pseudo-C2 symmetry about the C-N bond, with the bis-(tert-butoxy-carbon-yl)amino group twisted from the benzene ring plane by ca 60° and the bulky tert-butoxy-carbonyl (Boc) groups are orientated away from the substituted aniline group. As part of an anti-bacterial drug discovery programme furnishing analogues of platensimycin, we unexpectedly synthesized the bis-Boc-protected aniline.

Project description:The centrosymmetric title compound, [Pd(2)Cl(2)(C(27)H(26)N)(2)], was obtained by a C-H bond-activation reaction of a Schiff base ligand with Li(2)PdCl(4) in methanol, and was crystallized from dichloro-methane as orange crystals. The Pd atom displays a slightly distorted square-planar geometry, with the N- and C-atom donors in a cis arrangement.

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.

{[2-Methyl-2-(phen-oxy-meth-yl)propane-1,3-di-yl]bis-(-oxy)}di-benzene.

Project description:The title compound, C23H24O3, was obtained in a one-step (60% yield) synthesis from 1,1,1-tris(hydroxymethyl)ethane. It features a tripodal ligand capable of complexing metal centres. One of the three conformations involving the methyl group, the central C-C bond and the phenoxy substituents is antiperiplanar while the two others are synclinal [the corresponding C-C-C-O torsion angles are -174.6?(1), -53.2?(2) and -47.3?(2)°]. In the crystal, C-H?O inter-actions link the molecules into [010] chains.

2-[3,5-Bis(4-meth-oxy-phen-yl)-4,5-di-hydro-1H-pyrazol-1-yl]-4,6-bis-(4-meth-oxy-phen-yl)pyrimidine.

Project description:In the title compound, C(35)H(32)N(4)O(4), the pyrazole ring forms a dihedral angle of 15.04?(8)° with the adjacent pyrimidine ring.

The crystal packing features ?-? inter-actions, the centroid-centroid distance between the pyrimidine and methoxyphenyl rings being 3.604?(1)?Å. The pyrazole ring is nearly planar, with a maximum deviation of 0.020?(3)?Å for the -CH(2)- carbon.

Crystal structure of (n-but-yl)[2-(2,6-di-meth-oxy-phen-yl)-6-methyl-phen-yl](2-meth-oxy-phen-yl)phospho-nium chloride monohydrate.

Project description:The title hydrated salt, C26H32O3P(+)·Cl(-)·H2O, contains four different substit-uents (H, alkyl, aryl, and biar-yl) on the P atom. The P-H hydrogen atom of the phospho-nium ion was located in a difference Fourier map and refined without imposing additional restraints. In the crystal, the Cl(-) ions and water mol-ecules are linked by pairs of Owater-H⋯Cl(-) hydrogen bonds and further linked to the phospho-nium cation by P-H(+)⋯Cl(-) and CAr/OMe-H⋯Owater hydrogen bonds to form an infinite one-dimensional chain along the [010] direction.
