Crystal structure of an ordered [WOF5]- salt: (1,10-phen-H)[WOF5] (1,10-phen = 1,10-phenanthroline).

ABSTRACT: Crystals of 1,10-phenanthrolinium penta-fluorido-oxidotungstate(VI), (1,10-phen-H)[WOF5] (1,10-phen = 1,10-phenanthroline, C12H8N2), were obtained upon hydrolysis of WF6(1,10-phen) in CH3CN at 193?K. The (1,10-phen-H)[WOF5] salt contains a rare example of a [WOF5]- anion in which the oxygen and fluorine atoms are ordered. This ordering was verified by bond-valence determinations and structural comparisons with [Xe2F11][WOF5] and Lewis acid-base adducts of WOF4 with main-group donor ligands. The crystal packing is controlled by N-H?F hydrogen bonding that is directed exclusively to the axial F atom as a result of its increased basicity caused by the trans influence of the oxido ligand.

Crystal structure of 11-[4-(hex-yloxy)phen-yl]-1,2,4-triazolo[4,3-a][1,10]phenanthroline.

Project description:The title compound, C25H24N4O, was prepared from 2-chloro-phenanthroline and hexyl-oxyphenyl-tetra-zole. The main difference between the two independent mol-ecules (A and B) in the asymmetric unit is the orientation of the all-anti-configured hex-yloxy chain: in A the C-O-C-C torsion angle is 175.9 (2)° whereas it is -88.3 (3)° in B. The benzene substitution in the bay of the triazolophenanthroline results in a helical distorsion of the heterocyclic core, the dihedral angles between the mean planes formed by quinoline and benzotriazole ring systems are 13.73 (9) for mol-ecule A and 14.87 (8)° for B. The dihedral angles between the triazole ring and the attached benzene ring are 45.87 (15) in A and 53.93 (14)° in B. The angular annulation of four rings and the benzene substituent results in a helical distortion of the aromatic framework. The crystal is formed from layers composed of centrosymmetric pairs of A 2, B 2 mol-ecules with inter-digitating alkyl chains.

2-(2,4,6-Trimethyl-phen-yl)-1,10-phenanthroline.

Project description:In the title mol-ecule, C(21)H(18)N(2), the mean plane of the benzene ring of the mesityl group forms a dihedral angle of 82.69 (4)° with that of the phenanthroline ring system. The crystal structure is stabilized by π-π stacking inter-actions between the phenanthroline system and the benzene ring of the mesityl group of a symmetry-related mol-ecule, with centroid-centroid distances of 3.7776 (14) and 3.7155 (13) Å.

A NMR-Based Metabolomic Approach to Investigate the Antitumor Effects of the Novel [Pt(η 1-C2H4OMe)(DMSO)(phen)]+ (phen = 1,10-Phenanthroline) Compound on Neuroblastoma Cancer Cells.

Project description:NMR-based metabolomics is a very effective tool to assess the tumor response to drugs by providing insights for their mode of action. Recently, a novel Pt(II) complex, [Pt(ƞ1-C2H4OMe)(DMSO)(phen)]+ (phen = 1,10-phenanthroline), Pt-EtOMeSOphen, was synthesized and studied for its antitumor activity against eight human cancer cell lines. Pt-EtOMeSOphen showed higher cytotoxic effects than cisplatin in most of the cancer cell lines and in particular against the neuroblastoma cell line (SH-SY5Y). In this study, the mechanism of action of Pt-EtOMeSOphen on SH-SY5Y cells was investigated using 1H NMR-based metabolomics and compared with cisplatin. The observed time response of SH-SY5Y cells under treatment revealed a faster action of Pt-EtOMeSOphen compared with cisplatin, with a response already observed after six hours of exposure, suggesting a cytosolic target. NMR-based metabolomics demonstrated a peculiar alteration of the glutathione metabolism pathway and the diacylglycerol expression.

Palladium(II) complexes of 1,10-phenanthroline: Synthesis and X-ray crystal structure determination.

Project description:Two palladium(II) complexes, [Pd(phen)(N identical withCCH(3))(2)][O(3)SCF(3)](2) (1) and [Pd(phen)(mu-OH)](2)[O(3)SCF(3)](2).2H(2)O (2) (where phen= 1,10-phenanthroline), have been crystallized following the reaction of Pd(phen)Cl(2) with silver triflate, Ag(O(3)SCF(3)), in acetonitrile and water, respectively. The structures of both complexes are based on a Pd(phen)(2+) metal core, with two acetonitrile molecules binding in a monodentate fashion in complex 1 and two hydroxo bridges holding together two cores to form a dimer in complex 2. Additionally, both complexes present a hydrogen bonded 3-D network involving the triflate anions in 1, and water and triflate anions in 2. Both complexes have been characterized by infrared and (1)H NMR spectroscopy and their crystal structures determined by X-ray crystallography.

Diaqua-bis(1,10-phenanthroline)magnesium dichromate(VI) 1,10-phenanthroline disolvate.

Project description:In the title compound, [Mg(C(12)H(8)N(2))(2)(H(2)O)(2)][Cr(2)O(7)]·2C(12)H(8)N(2), the cation and anion are situated on a twofold rotation axis. The Mg(II) ion is coordinated by four N atoms from two 1,10-phenanthroline ligands and two O atoms from coordinated water mol-ecules in a distorted octa-hedral geometry. Inter-molecular O-H⋯N and O-H⋯O hydrogen bonds and π-π inter-actions between the aromatic rings [shortest centroid-centroid separation = 3.527 (2) Å] link the cations, anions and 1,10-phenanthroline solvent mol-ecules into a hydrogen-bonded cluster.

Crystal structure of (nitrato-κO)bis-(1,10'-phenanthroline-κ2N,N')copper(II) nitrate gallic acid monosolvate monohydrate.

Project description:The title compound, [Cu(NO3)(C12H8N2)2]NO3·C7H6O5·H2O, consists of a mononuclear complex cation with the central CuII atom in a distorted trigonal-bipyramidal coordination sphere. Two N atoms of two 1,10-phenanthroline ligands occupy the axial sites, and the remaining N atoms of the two ligands, as well as one nitrate O atom the equatorial positions. One mol-ecule each of gallic acid and water are present in the crystal as solvent mol-ecules that do not coordinate to the CuII cation, just as the nitrate counter-anion. In the crystal, inter-molecular O-H⋯O hydrogen bonds, as well as C-H⋯O inter-actions and π-π ring stacking between benzene and pyridine rings [centroid-to-centroid distances = 3.471 (2), 3.559 (2) and 3.790 (2) Å], link the mol-ecules into a three-dimensional network structure.

Crystal structure of aqua-bis-(hepta-fluoro-butano-ato-?O)(1,10'-phenanthroline-?(2) N,N')copper(II).

Project description:The title compound, [Cu(C4F7O2)2(C12H8N2)(H2O)], is mononuclear and contains a penta-coordinated Cu(II) ion.

Crystal structure of bis-[di-hydro-bis-(pyrazol-1-yl)borato-?2 N 2,N 2'](1,10-phenanthroline-?2 N,N')zinc(II).

Project description:The asymmetric unit of the title compound, [Zn(C6H8N4B)2(C12H8N2)], comprises one half of a ZnII cation (site symmetry 2), one di-hydro-bis-(pyrazol-1-yl)borate ligand in a general position, and one half of a phenanthroline ligand, the other half being completed by twofold rotation symmetry. The ZnII cation is coordinated in form of a slightly distorted octa-hedron by the N atoms of a phenanthroline ligand and by two pairs of N atoms of symmetry-related di-hydro-bis-(pyrazol-1-yl)borate ligands. The discrete complexes are arranged into columns that elongate in the c-axis direction with a parallel alignment of the phenanthroline ligands, indicating weak ?-? inter-actions.
