2-Methoxy-5-phenylaniline, a promissor monomer for PANI studies, has been characterized by single-crystal X-ray diffraction at two temperatures: orthorhombic, space group P212121, Z = 12 with a = 5.9900(2) Å, b = 20.4873(6) Å, c = 26.3727(8) Å and R = 0.0868 for 293(2) K and a = 5.8337(9) Å, b = 20.4428(31) Å, c = 26.0773(40) Å and R = 0.0669 for 120(2) K.(More)
Compounds of the mevalonate pathway containing a terminal di- or triphosphate (mev-PP or mev-PPP) were tested as substrates of several enzyme ligases (T4 RNA ligase, T4 DNA ligase, firefly luciferase and other ligases) for the synthesis of ATP derivatives of the mev-pppA or mev-ppppA type. T4 RNA ligase, in the presence of ATP and the substrates: geranyl,(More)
In the title compound, [Cu(SO(4))(C(10)H(9)NO(2))(2)]·2H(2)O, the Cu(II) ion is chelated by two (2-quinol-yl)methane-diol ligands and coordinated by a monodentate sulfate ligand in a distorted trigonal-bipyramidal environment, with O atoms occupying the equatorial sites and N atoms in the axial sites. The dihedral angle between the two essentially planar(More)
In the crystal structure of the title compound, C(12)H(10)N(6), the mol-ecules deviate slightly from planarity. The plane of the central triazole ring makes angles of 6.13 (9) and 3.28 (10)° with the pyridyl ring planes. Intra-molecular N-H⋯N inter-actions form six-membered closed rings. The crystal packing also shows weak C-H⋯π and C-H⋯N inter-actions.
The crystal structure of the title compound, [Mn(C(7)H(5)O(2))(C(10)H(6)NO(2))(C(10)H(7)NO(2))], contains manganese(II) ions six-coordinated in a distorted octa-hedral environment. The equatorial plane is occupied by four O atoms, two from the carboxyl-ate group of the benzoate ion, the other two from carboxyl-ate/carboxyl groups of the quinaldate/quinaldic(More)
The crystal structure of the title compound, [Cu(C10H6NO2)(C7H5O2)(C10H7NO2)], contains copper(II) ions five-coordinated in a distorted trigonal-bipyramidal environment. The equatorial plane is occupied by three O atoms, one from the carboxylate group of the benzoate ion considered as occupying a single coordination site, the other two from two carboxylate(More)

The title compound, C(20)H(26)N(4), is composed of two (6-methyl-2-pyridyl)methyl-ene units linked by a 1,6-diamine hexane chain. The mol-ecule has C(i) symmetry with the inversion center situated at the mid-point of the central C-C bond. The alkyl chain has an all-trans conformation, with all the non-H atoms sharing the same plane [maximum deviation 0.004(More)
In the monomeric title complex, [Cu(C(6)H(3)BrNO(2))(NO(3))(H(2)O)(2)], the Cu(II) ion is coordinated by a bidentate 6-bromo-picolinate ion, one nitrate ion and two water mol-ecules in a geometry inter-mediate between five- and six-coordinate. Conventional O-H⋯O hydrogen bonds link the complex mol-ecules, forming layers parallel to the ab plane.
