Two new examples of mixed metal copper(I) sulfites, namely, Na3Mn2Cu(SO3)4(H2O)5 (1) and NaMn4Cu(SO3)5(H2O)3 (2), have been synthesized and structurally characterized. The 1D structure of 1 is built from a chain of [Mn2Cu(SO3)4]3- bridged by Na+ ions whereas the structure of 2 features a complicated 3D framework in which Mn8O36 octanuclear clusters are bridged by sulfite anions and copper(I) io...

A general, new principle for the design of noncentrosymmetric solids is evident in the packing of helical metal-oxyfluoride chains in Zn(C4H4N2)(H2O)2MoO2F4 (C4H4N2 ) pyrazine, pyz). Each inorganic helical chain comprises alternating Znand Mocentered octahedra and interleaves with six more helices of the same handedness through Zn-pyrazine-Zn bridges. From comparisons with similar structures wh...

van der Waals cluster (SO2)n is investigated by using single photon ionization of a 26.5 eV soft x-ray laser. During the ionization process, neutral clusters suffer a small fragmentation because almost all energy is taken away by the photoelectron and a small part of the photon energy is deposited into the (SO2)n cluster. The distribution of (SO2)n clusters decreases roughly exponentially with ...

Abstract. Although knowledge of the physical state aerosol particles is essential to understand atmospheric chemistry model and measurements, information on viscosity consisting organic inorganic salts still rare. Herein, we quantified viscosities at 293 ± 1 K upon dehydration for binary systems, sucrose–H2O ammonium sulfate (AS)–H2O, ternary sucrose–AS–H2O organic-to-inorganic dry mass ratios ...

Three 3D lanthanide–organic frameworks (LOFs), [LnL(HCO2)(DMF)]n (Ln = Eu (1), Gd (2), Dy (3); H2L = 2,2′-dimethoxy-4,4′-biphenyldicarboxylic acid), have been prepared by the solvothermal reaction of Ln(NO3)3·6H2O and H2L in DMF–H2O mixed solvent. Crystallographic data show that LOFs 1–3 are isomorphous and crystallize in the orthorhombic space group Pna21. Each Ln(III) is eight-coordinated to ...

Energetics and geometrical structures of neutral, (H2O)n, and ionized, (H2O)n, water clusters, with n ) 2-5, are investigated using local-spin-density functional electronic structure calculations with exchange-correlation gradient corrections. While the ground-state structures of the neutral clusters are hydrogen-bonded cyclic ones, those of the molecular ions are noncyclic. The lowest energy i...

Organic and inorganic clusteroluminescence have attracted great attention while the underlying mechanisms is still not well understood. Here, we employed a series of ancient complexes platinocyanides with aggregation-induced emission property to elucidate mechanism including how does chromophore form solid structures influence luminescence behaviors. The results indicate that isolated platinocy...

The asymmetric unit of the title inorganic-organic hybrid compound, (C10H16N2O)[CoCl4]·H2O, consists of a tetrahedral [CoCl4](2-) anion, together with a [C10H18N2O](2+) cation and a water mol-ecule. Crystal cohesion is achieved through N-H⋯Cl, O-H⋯Cl and N-H⋯O hydrogen bonds between organic cations, inorganic anions and the water mol-ecules, building up a three-dimensional network.

Nine new coordination polymers: [Cu3(ipO),(pyz)2](5), [Cu3(ipO)2(4-phpy)(H2O)2](6), [Cu(ip)(4-phpy)2] (7), [Cu3(ipO)2(H2O)2](8), [Co(phen)(ip)(H2O)](9), [Co3(1,2,3-btc)2(4,4'-bpy)2(H2O)2].2H2O(10), [Ni(1,2,3-btcH)(4,4'-bpy)(H2O)].H2O(11), [Cd5(1,2,3-btc),(1,2,3-btcH)2(4,4'-bpy)3(H2O)2] (12) and (1,2,3-btcH3)(4,4'-bpy) (13)(1,2,3-btcH3 = 1,2,3-benzenetricarboxylic acid, ipO = 2-hydroxyisophthala...

The aim of this study was to investigate the comparison between some seminal plasma parameters and age of the bull. Concentrations of various biochemical parameters like fructose, glucose, total proteins, albumin and inorganic ions including Na, K and Cl ions of seminal plasma of breeding Sahiwal bulls of different ageswere assessed. Methods: 40Sahiwal bullsdivided into 4 age groups.Semen (2ml ...
