In the title compound, 2Na(+)·C(9)H(3)NO(8) (2-)·3H(2)O, the asymmetric unit consists of two Na(+) cations, one dihydrogen pyridine-2,3,5,6-tetra-carboxyl-ate dianion (H(2)pdtc(2-)) and three water mol-ecules coordinated to the Na(+) cations. The configuration of the anion is stabilized by intramolecular O-H⋯O hydrogen bonding between vicinal carboxylate/carboxy groups. The Na(+) cations are br...

The title compound, (C(7)H(9)N(2)O(2))(2)[HgCl(4)], self-assembles into cationic organic bilayers containing the 2-methyl-4-nitro-anilinium cations, sandwiched between anionic inorganic layers built up by the distorted tetra-hedral [HgCl(4)](2-) groups. The organic sheets are inter-linked through weak C-H⋯O hydrogen bonds, while they inter-act with the anionic part via strong charge-assisted N(...

The title compound, [CuCl(C(9)H(9)N(5))](n), prepared by solvo-thermal synthesis, is a new homometallic Cu(I)-olefin coordination polymer in which the Cu(I) atoms are linked by the 3-(2-allyl-2H-tetra-zol-5-yl)pyridine ligands and are each bonded to one terminal Cl atom. The organic ligand acts as a bidentate ligand bridging two neighboring Cu centers through the bonds to the N atom of the pyri...

In the title compound, C(19)H(15)N(4) (+)·Br(-)·C(2)H(5)OH, the tetra-zole ring makes dihedral angles of 57.44 (9), 50.92 (9) and 4.65 (8)° with the attached phenyl rings. In the crystal, the cation and the anion are linked to each other by inter-molecular C-H⋯Br hydrogen bonds into an infinite chain along the b axis. The anion and the ethanol solvent mol-ecule are linked by an O-H⋯Br hydrogen ...

In the title compound, [Sn(C(6)H(5))(3)(C(9)H(10)NO(2))], the Sn atom is coordinated by three phenyl groups and a carboxyl-ate anion in a distorted tetra-hedral geometry. An intra-molecular C-H⋯O inter-action forms an S(7) ring motif. The dihedral angles between the benzoate group and the other three phenyl rings are 76.94 (8), 66.82 (8) and 42.34 (9)°. The crystal structure is further stabiliz...

The highly diastereoselective anti-aminohydroxylation of (E)-gamma-tri-iso-propylsilyloxy-alpha,beta-unsaturated esters, via conjugate addition of lithium (S)-N-benzyl-N-(alpha-methylbenzyl)amide and subsequent in situ enolate oxidation with (+)-(camphorsulfonyl)oxaziridine, has been used as the key step in the asymmetric synthesis of N,O,O,O-tetra-acetyl d-lyxo-phytosphingosine (20% yield over...

In the title compound, [ZnBr(2)(C(12)H(9)N(3)O(2))], the Zn(II) ion is bonded to two Br ions and two N atoms of the diimine ligand in a distorted tetra-hedral geometry. With the exception of the Br atoms, all other atoms are disordered over two sets of sites corresponding to a 180° rotation of the mol-ecule along [[Formula: see text]02]. The refined occupancies of the components are 0.809 (2) a...

For the last fifteen years, on-surface synthesis became an extremely popular and powerful method to fabricate nanostructures which otherwise would not have been accessible by conventional wet organic syntheses. The syntheses, realized in chamber of high vacuum scanning tunneling microscope (STM), permitted fabrication characterization atomically defined such as polycyclic aromatic hydrocarbons ...

9-Chloro and 9-amino-2-methoxyacridines bearing different substituents in position 7, as well as their corresponding unsubstituted dimeric and tetrameric complexes, were investigated for in vitro antiproliferative properties against Leishmania infantum compared to toxicity towards human monocytes. The results clearly confirmed that several compounds of the 2-methoxyacridine series, together wit...

In the mol-ecule of the title compound, [Co(C(44)H(24)Cl(4)N(4)){(C(4)H(9))(3)P}(2)]ClO(4), the Co(III) centre has a slightly distorted octa-hedral geometry and is coordinated by four N atoms of the tetra-pyrrolic ring in the equatorial positions and two phosphine ligands in the axial positions. The dihedral angles between meso-substituted chloro-phenyl rings and the basic tetra-pyrrolic ring a...
