Four new [NiH2L](ClO4)2 (1), [CuH2L](ClO4)2 (2), [MnH2L](ClO4)2 (3) and [CdH2L](ClO4)2 (4), complexes were prepared by the reaction of a new Schiff base ligand and Cu(II), Ni(II), Mn (II) and Zn (II) metal ions in equemolar ratios. The ligand, H2L was synthesized by reaction of 1, 4- bis (2- formylphenyl) piperazine and ethanol amine and characterized with IR and 1H,13C NMR spectroscopy. All co...

The present work describes the studies on the coordination behaviour of 4[N-(benzalidene) amino]antipyrine semicarbazone (BAAPS) (I), 4[N-(furfural)amino]antipyrine semicarbazone (FFAAPS) (II) and 4[N-(cinnamalidene)amino]antipyrine semicarbazone (CAAPS) (III) in presence of dimethyl sulfoxide (DMSO) or diphenyl sulfoxide (DPSO) towards Th4+ and UO22+ salts. All the complexes were isolate...

Confined excitonic complexes in two dimensions, consisting of Ne electrons and Nh holes, are studied by means of Bethe-Goldstone equations. Systems with up to twelve pairs, and asymmetric configurations with Ne 6= Nh are considered. The weak confinement regime gives indication of weak binding or even unbinding in the triexciton and the four-exciton system, and binding in the higher complexes. P...

Mashhad city is located on alluvial deposits where the expanded area of this city, especially the central and eastern areas surrounding Imam Reza holy shrine, are built on weak and fine-grained deposits. Therefore, the soil improvement would be inevitable due to construction of high-rise buildings such as hotels and commercial complexes in these areas, as well as restructuring old buildin...

Various factors affect the degree of mass crime of an environment, including social, economic, and physical factors. The purpose of this research is to investigate the role of the physical components of an environment on mass crime rate. In this regard, open spaces between residential complexes were selected as the case studies and based on five outdoor patterns including linear pattern, disper...

To the central atom of the title compound, [HgBr(C(16)H(18)N(3)O(2))], is attached one bromide ion and a 1,3-bis-(2-ethoxy-phen-yl)triazenide ligand through one O and two N atoms, forming a distorted square-planar geometry around the Hg(II) atom. The mononuclear complexes are linked into centrosymmetric dimers by non-classical inter-molecular C-H⋯N hydrogen bonds and by weak Hg-η(3)-arene π-int...

In the title dinuclear complex, [Cu(2)(C(19)H(11)N(3)O(3)S)(C(5)H(5)N)(2)], the two Cu(II) centers have different coordination environments, viz. N(2)OS and N(2)O(2), each exhibiting a distorted square-planar geometry. π-π inter-actions between the aromatic rings of neighbouring complexes [centroid-centroid distance = 3.856 (5) Å] link pairs of mol-ecules into centrosymmetric dimers, which are ...

Two cochain complexes are constructed for an algebra A and a coalgebra C entwined with each other via the map ψ : C ⊗ A → A ⊗ C. One complex is associated to an A-bimodule, the other to a C-bicomodule. In the former case the resulting complex can be considered as a ψ-twisted Hochschild complex of A, while for the latter one obtains a ψ-twist of the Cartier complex of C. The notion of a weak com...

Peripheral events in olfaction involve odorant binding proteins (OBPs) whose role in the recognition of different volatile chemicals is yet unclear. Here we report on the sensitive and quantitative measurement of the weak interactions associated with neutral enantiomers differentially binding to OBPs immobilized through a self-assembled monolayer to the gate of an organic bio-electronic transis...
