The reaction between [Ru 2 Cl ( my -Cl) (CO) 6 ] and the biradicaloid [P( -NTer)] proceeds under insertion of a Ru(II)Cl(CO) fragment into one P-N bond addition chloride to adjacent phosphorus center. Thereby an unprecedented ruthenacycle is obtained that was investigated by single crystal X-ray analysis, NMR IR spectroscopy DFT calculations. reactivity complex in halide-pseudo-halide exchange ...

Mechanochemical reaction of solid piracetam with the inorganic salts LiCl and LiBr yields ionic co-crystals which are also co-drugs, characterized by markedly different thermal properties with respect to pure components, also depending on the method for preparation and/or conditions of measurements; single crystal and powder X-ray diffraction at variable temperatures, DSC, TGA, hot stage micros...

We report on the synthesis, crystal structure and magnetic properties of a previously unreported Co(2+) S = 3/2 compound, (C4H12N2)[CoCl4], based upon a tetrahedral crystalline environment. The S = 3/2 magnetic ground state of Co(2+), measured with magnetization, implies an absence of spin-orbit coupling and orbital degeneracy. This contrasts with compounds based upon an octahedral and even kno...

The crystal and molecular structures of [bis(5-chloro-2methoxybenzoate)tetraaquamanganese(II)], [pentaaqua(5-chloro-2-methoxybenzoato)cobalt(II)] (5chloro-2-methoxybenzoate), [pentaaqua(5-chloro-2-methoxybenzoato)nickel(II)] (5-chloro-2methoxybenzoate) and [aquabis(5-chloro-2-methoxybenzoate)zinc(II)] monohydrate were determined by a single-crystal X-ray analysis. Mn(H2O)4L2 (where L = C8H6ClO3...

A four-electron-reduced ruthenium(ii) NADH-type complex, [Ru(bbnpH4)(CO)2Cl](PF6) (bbnpH4 = 2,2'-(4-(tert-butyl)pyridine-2,6-diyl)bis(5,10-dihydrobenzo[b][1,5]naphthyridine)), has been successfully synthesized by mixing an NAD+-type ligand, bbnp (bbnp = 2,2'-(4-(tert-butyl)pyridine-2,6-diyl)bis(benzo[b][1,5]naphthyridine)), and [Ru(CO)2Cl2] under moderate water-gas-shift reaction conditions, wh...

Seventeen new halogen-bonded co-crystals characterized by single crystal X-ray analysis are presented from 8 × 4 combinations using methyl-substituted pyridine N-oxides and 1,ω-diiodoperfluoroalkanes. The N−O group in six of 17 co-crystals is monodentate and 11 have μ-O,O bidentate halogen bond acceptor modes. Remarkably, the N−O group in co-crystals of 3-methyl-, 4-methyland 3,4-dimethylpyridi...
