A series of six novel mononuclear, binuclear and linear one-dimensional (1D) compounds of copper(II) with chloranilic acid (3,6-dichloro-2,5-dihydroxybenzoquinone, H2CA) is prepared and a design strategy for the preparation of such complexes is discussed. Four described compounds are linear 1D coordination polymers [Cu(CA)]n, whereas another two involve a binuclear and a mononuclear, Cu2(CA)3 a...

The structures of the solvated zinc ion and the solvated zinc-iodide complexes in methanol solution have been determined by EXAFS. The zinc ion is six-coordinated in an octahedral fashion with a mean Zn-O bond distance of 2.071(4) Å. According to the stability constants of the zinc-iodide system in methanol solution the first complex, ZnI+, is suppressed, which may indicate that a coordination ...

An X-ray crystallographic study demonstrated that the tris complex of Al3+ with 2-methyl-8-quinolinol (Hmq), [Al(mq)3], had a discrete octahedral geometry in a meridional configuration with respect to mq-; the Al-N bonds were appreciably elongated. In organic solvents, the complex reacted with water to give a lower species of a mu-oxo dimer, [Al2O(mq)4], and a protonated ligand, depending on th...

A six-coordinate manganese (II) complex with the tripod ligand tris(2-benzimidazolylmethyl)amine (ntb), with composition [Mn(ntb) (4-hydroxycinnamate)](4-hydroxycinnamate) · (DMF)0.5 · (H2O)3, was synthesized and characterized by elemental and thermal analyses, electrical conductivity, IR, and UV/vis spectral measurements. The crystal structure of the complex has been determined by the single-c...

Potassium (K) fixation by phyllosilicates clay minerals is a very important process influencing the availability of K for plants. Information about K fixation is limited in Hamadan soils. The objectives of this research were to determine potassium fixation capacity (PFC) and potassium fixation index (PFI) of 10 surface soils of Hamadan province and the correlation of these parameters with soil ...

The resurgence of the molten-salt nuclear reactors (MSRs) creates interesting problems in chemistry. As MSRs operate, composition and physical properties salts change because fission corrosion. Since Cr is principal corrosion product NaCl a common constituent, we studied atomic structure molten NaCl–CrCl3. We found networks CrCl63– octahedra an intermediate-range order with nonmonotonic tempera...

In this paper, we enumerate the parameter matrices of all perfect $2$-colorings of the Platonic graphs consisting of the tetrahedral graph, the cubical graph, the octahedral graph, the dodecahedral graph, and  the icosahedral graph.
