In the title compound, (C(7)H(18)N(2)O)[ZnCl(4)], the Zn(II) ion is coordinated by four Cl atoms in a close to tetra-hedral geometry. The crystal packing exhibits C-H⋯Cl, N-H⋯Cl and N-H⋯O hydrogen bonds.
The powder of the arene osmium(II) complex, [Os(II)(dpzm)(η6-p-cym)Cl]BF4 (dpzm = di(1H-pyrazol-1-yl)methane; η6-p-cym para-cymene), with a formula C17H22BClF4N4Os (referred to herein as 1) was isolated from reaction [(η6-p-cym)Os(μ-Cl)(Cl)]2 dpzm dissolved in acetonitrile and under flow nitrogen gas. It characterized by spectroscopic techniques (viz., FTIR, 1H NMR, UV-Visible absorption). Yell...
زمینه و هدف: مال اکلوژن cl ii یکی از ناهنجاری های شایع در جوامع مختلف انسانی بوده و استفاده از یک روش ساده، ارزان و قابل دسترس درمانی که بتوان آن را توسط دندانپزشک عمومی یا متخصص ارائه نمود، در پیشگیری از عوارض آتی مال اکلوژن بسیار حیاتی است. درمان ناهنجاری cl ii با استفاده از دستگاه های فانکشنال نظیر twin block و بایت پلن شیب دار در مقایسه با درمان های ارتودنسی ثابت یا ارتوسرجری؛ هزینه، عوارض ...

In this work, the efficiency, generality and applicability of new Bronsted acidic ionic liquid (BAIL) 1-methyl-3-(2-(sulfooxy)ethyl)-1H-imidazol-3-ium chloride {[Msei]Cl} as heterogeneous and green catalyst for organic transformations are studied. Herein, the following one-pot multi-component reactions in the presence of [Msei]Cl are investigated: (i) the synthesis of quinoxaline derivatives fr...
this work is presented in five parts. in the first part preparation of the starting complex [pt(c^n)cl(dmso)], 1, in which c^n = n(1),c(2?)-chelated, deprotonated 2-phenylpyridine, and dmso = dimethylsulfoxide, and its reaction with 1 equiv of the biphosphine ligands bis(diphenylphosphino)amine, dppa, or bis(diphenylphosphino)methane, dppm, to give the complex [pt(c^n)cl(dppa)], 2, or [pt(c^n)c...
ABSTRACT: It's been more than a century that third molar has drown the attention of orthodontists . This attention has been based on two main reasons: 1- The probable role of third molar in making late crowding or Recrowding of lower anterior teeth 2- Evaluation of causative factors and prediction of impaction of this tooth and orthodontic 's help to prevention of problems caused by this too...
The formation of a new semicarbazone Schiff-base ligand (E)-2-(2-(phenyl(2-phenylhydrazinyl)- methyl)cyclohexylidene)hydrazine-1-carboxamide (HL) and its complexes are reported. was prepared from the condensation Mannich-base 2-(phenyl(2-phenylhydrazinyl)methyl)cyclohexan-1-one (M) with semicarbazide. A series metal were by reaction chlorides Cr(III), Mn(II), Co(II), Ni(II), Cu(II)), Zn(II) Cd(...
Inter-Coulombic decay (ICD) resonances in the photoionization of Cl@C60 endofullerene molecule are calculated using a perturbative density functional theory (DFT) method. This is first ICD study an open shell atom fullerene cage. Three classes probed: (i) Cl inner vacancies decaying through C60 outer continua, (ii) and (iii) either system continua Cl-C60 hybrid levels, Auger-ICD resonances. Com...
The reaction of the Tc(II) nitrosyl complex (Bu(4)N)[Tc(NO)Cl(4)] with Di-(2-picolyl)(NEt)amine in methanol yields the neutral complex [Tc(NO)Cl(py-N(Et)-py)]. The reaction of the Tc(I) nitrosyl complex [Tc(NO)Cl(2)(HOMe)(PPh(3))(2)] with this tridentate ligand yields cationic [Tc(NO)Cl(py-N(Et)-py)(PPh(3))]Cl. These two complexes have been structurally characterized. The reaction of [Tc(NO)Cl(...
