2-(Diphenylphosphinoylmethyl)pyrrole-2-(diphenylphosphinomethyl)pyrrole (0.43/0.57) and tetrachlorido(5-diphenylphosphinomethyl-2H-pyrrole-kappa(2)N,P)titanium(IV).

ABSTRACT: The title phosphine oxide-phosphine, 0.43C(17)H(16)NOP.0.57C(17)H(16)NP, (I)/(II), was obtained as a 0.861 (6):1.139 (6) cocrystallized mixture. Hydrogen bonding between the two constituents leads to the formation of 2:2 solid-state assemblies. Instead of forming the expected simple N,P-chelated system via loss of the N-bound H atom, reaction of 2-(diphenylphosphinomethyl)pyrrole, (II), with TiCl(4) leads to the formation of the title titanium(IV) complex, [TiCl(4)(C(17)H(16)NP)], (IV), containing a rearranged neutral ligand in which the N-bound H atom moves to one of the pyrrole C atoms, giving a partially unsaturated ring.

SAW Resonators and Filters Based on Sc0.43Al0.57N on Single Crystal and Polycrystalline Diamond.

Project description:The massive data transfer rates of nowadays mobile communication technologies demand devices not only with outstanding electric performances but with example stability in a wide range of conditions. Surface acoustic wave (SAW) devices provide a high Q-factor and properties inherent to the employed materials: thermal and chemical stability or low propagation losses. SAW resonators and filters based on Sc0.43Al0.57N synthetized by reactive magnetron sputtering on single crystal and polycrystalline diamond substrates were fabricated and evaluated. Our SAW resonators showed high electromechanical coupling coefficients for Rayleigh and Sezawa modes, propagating at 1.2 GHz and 2.3 GHz, respectively. Finally, SAW filters were fabricated on Sc0.43Al0.57N/diamond heterostructures, with working frequencies above 4.7 GHz and ~200 MHz bandwidths, confirming that these devices are promising candidates in developing 5G technology.

Bis(catecholato-κ2 O,O')bis-(dimethyl sulfoxide-κO)titanium(IV).

Project description:Bis(benzene-1,2-diolato-κ2 O,O')bis-(dimethyl sulfoxide-κO)titanium(IV), [Ti(C6H4O2)2(C2H6OS)2], crystallizes with two crystallographically independent mol-ecules in the space group P21/c emulating ortho-rhom-bic Pbca symmetry (β = 90.0445 (9)°]. The two mol-ecules are related by pseudo-glide symmetry, broken by modulation of each one catecholate and dimethyl sulfoxide (DMSO) ligand. Twinning by pseudomerohedry was observed [twin ratio 0.5499 (7):0.4401 (7)]. Complex 3 was obtained by heating of diprotonated titanium tris-catecholate precursor 2H in DMSO, by formal displacement of a catechol mol-ecule by two DMSO mol-ecules. Complex 3 is just the second heteroleptic, mono-nuclear, neutral bis-catecholate complex with TiO6 metal coordination, the only other one being its bis-DMF analogue 6. The two mol-ecules of 3 exhibit a distorted octa-hedral geometry. The geometry and distortions from ideal symmetry of 3 are discussed and compared to 6 and to cationic tris-catecholate titanium complexes.

Ge0.57Ti0.43O2: a new high-pressure material with rutile-type crystal structure.

Project description:Single crystals of a GeO2-TiO2 solid solution with the corresponding composition Ge0.57Ti0.43O2 (germanium titanium tetra-oxide) were obtained by devitrification of germania-titania glass at high pressure and temperature. The new compound crystallizes in the rutile structure type (space group P42/mnm), where Ge and Ti share the same position M (site symmetry m.mm), with occupancy values of 0.57?(3) and 0.43?(3), respectively, and one O-atom position (m.2m). The M site is in a sixfold O-atom coordination and, as in the original TiO2 rutile structure, an elongation of the O-M-O bonds along the c-axis direction of the coordination polyhedron and deviation of the angles from 90° lead to a decrease in the coordination symmetry from octa-hedral to tetra-gonal. The Ge and Ti atoms are fully disordered in the structure, which indicates that the rutile structure is surprisingly pliant given the differing sizes of the two cations.

(E)-1-[(2-Fluoro-phen-yl)imino-meth-yl]-2-naphthol-(Z)-1-[(2-fluoro-phen-yl)amino-methyl-idene]naphthalen-2(1H)-one (0.57/0.43).

Project description:The title Schiff base compound, 0.57C(17)H(12)FNO·0.43C(17)H(12)FNO, reveals both the enol (OH) and keto (NH) tautomeric forms with occupancies of 0.57?(6) and 0.43?(6), respectively. The tautomeric forms are stabilized by intra-molecular O-H?N (enol) and N-H?O (keto) hydrogen bonds. The dihedral angle between the naphthalene ring system and the benzene ring is 32.76?(1)°.

Titanium(IV) complexes: cytotoxicity and cellular uptake of titanium(IV) complexes on caco-2 cell line.

Project description:Replacement of the ancillary ligand in titanocene dichloride by amino acids provides titanocene species with high water solubility. As part of our research efforts in the area of titanium-based antitumor agents, we have investigated the cytotoxic activity of Cp(2)TiCl(2) and three water soluble titanocene-amino acid complexes - [Cp(2)Ti(aa)(2)]Cl(2) (aa=L-cysteine, L-methionine, and D-penicillamine) and one water soluble coordination compound, [Ti(4)(maltolato)(8)(micro-O)(4)] on the human colon adenocarcinoma cell line, Caco-2. At pH of 7.4 all titanocene species decompose extensively while [Ti(4)(maltolato)(8)(micro-O)(4)] is stable for over seven days. In terms of cytotoxicity, the [Cp(2)Ti(aa)(2)]Cl(2) and [Ti(4)(maltolato)(8)(micro-O)(4)] complexes exhibited slightly higher toxicity than titanocene dichloride at 24h, but at 72h titanocene dichloride and [Ti(4)(maltolato)(8)(micro-O)(4)] have higher cytotoxic activity. Cellular titanium uptake was quantified at various time intervals to investigate the possible relationship between Ti uptake and cellular toxicity. Results indicated that there was not a clear relationship between Ti uptake and cytotoxicity. A structure-activity relationship is discussed.

(3R,4S)-3,4-Isopropyl-idenedioxy-3,4-dihydro-2H-pyrrole 1-oxide.

Project description:The title compound C(7)H(11)NO(3) was prepared by intra-molecular nucleophilic displacement of 2,3-O-iso-propyl-idene-d-erythronolactol. There are two mol-ecules in the asymmetric unit, which are related by a pseudo-inversion centre. The crystal structure determination confirms unequivocally the configuration of the chiral centres as 3S,4R. In the crystal structure, inter-molecular C-H?O inter-actions link the mol-ecules (into infinite zigzag chains along the a axis.

Transformation of Tri-Titanium(IV)-Substituted ?-Keggin Polyoxometalate (POM) into Tetra-Titanium(IV)-Substituted POMs : Reaction Products of Titanium(IV) Sulfate with the Dimeric Keggin POM Precursor under Acidic Conditions

Project description:Reaction products of titanium(IV) sulfate in HCl-acidic aqueous solution with the dimeric species linked through three intermolecular Ti-O-Ti bonds of the two tri-titanium(IV)-substituted ?-Keggin polyoxometalate (POM) subunits are described. Two novel titanium(IV)-containing ?-Keggin POMs were obtained under different conditions. One product was a dimeric species through two intermolecular Ti-O-Ti bonds of the two tetra-titanium(IV)-substituted ?-Keggin POM subunits, i.e., [[{Ti(H2O)3}2(?-O)](?-PW9Ti2O38)]26- (1). The other product was a monomeric ?-Keggin species containing the tetra-titanium(IV) oxide cluster and two coordinated sulfate ions, i.e., [{Ti4(?-O)3(SO4)2(H2O)8}(?-PW9O34)]3- (2). Molecular structures of 1 and 2 were also discussed based on host (lacunary site)-guest (titanium atom) chemistry.

(3R,4S)-3,4-Isopropylidenedioxy-5-phenylsulfonylmethyl-3,4-dihydro-2H-pyrrole 1-oxide.

Project description:The title compound, C(14)H(17)NO(5)S, was prepared by oxidation of (2R,3S,4R)-2-phenyl-sulfonyl-methyl-1-hy-droxy-3,4-iso-pro-pyl-idene-dioxy-pyrrolidine. Its crystal structure confirms unequivocally its configuration. Two inter-molecular C-H?O inter-actions help to establish the packing.

Tetra-kis(N,N-diethyl-carbamato)titanium(IV).

Project description:The mononuclear title compound, [Ti(C(5)H(10)NO(2))(4)], is a rare example of an eight-coordinate Ti(IV) compound in which all donor atoms are O atoms. The coordination geometry around Ti(IV) is pseudo-dodeca-hedral and the O-C-O angles of the carbamate ligands are slightly compressed [range 115.3 (2)-116.7 (2)°], apparently on account of the high coordination number. One ethyl group is disordered over two positions; the site occupancy factors are 0.64 and 0.36.
