A new binuclear paddle-wheel palladium(II) complex of [Pd2(μ-mtzt)4]dmgH2 (1) has been prepared by the treatment of PdCl2 in acetonitrile with mixture of 1-methyl-1H-1,2,3,4-tetrazole-5-thiol (Hmtzt) and dimethylglyoxime (dmgH2) in methanol. Resulted complex was characterized by elemental analysis (CHNS), IR, UV–Vis absorption, 1H NMR spectroscopy and its structure was determined with single-cr...
We present X-ray photoelectron, Co $${{L}_{{2,3}}}$$ and O K absorption, as well $$K{{\beta }_{{1,3}}}$$ emission spectroscopy results of studies the spin states trivalent cobalt ions in single-crystal cobaltite LaCoO 3 . show that at room temperature, bulk a single crystal, 3+ are low-spin state, while high-spin 2+ , probably also intermediate-spin located on surface.
in this thesis, phosphorus ylides [phbppy], [no2bppy] and [brbppy] have been synthesized through the formation of phosphonium salt and dihydrogenation, followed by the reaction of pd(oac)2 and the orthopalladated dinuclear complexes [pd(?-cl)(phbppy)]2, [pd(?-cl)(no2bppy)]2 and [pd(?-cl)(brbppy)]2 have been produced. the reaction of dinuclear complexes and bidentate ligands [l = bipy (2,2-bipyr...
Polar organic nonlinear optical material, L-tartaric acid single crystals have been grown from slow evaporation solution growth technique. Single crystal X-ray diffraction study indicates that the grown crystal crystallized in monoclinic system with space group P21. Crystalline perfection of the crystal has been evaluated by high resolution X-ray diffraction technique and it reveals that the cr...
We report the synthesis and single crystal X-ray analysis of C(84) ().AgTPP (Ag tetraphenylporphyrin) cocrystal-the first ordered crystal structure containing a pristine higher fullerene.
Optical quality single crystals of glycine thiourea (GT), a new organic nonlinear optical (NLO) crystal, were grown from aqueous solution by slow evaporation method. Solubility of GT was determined at various temperatures. Single crystal X-ray diffraction studies indicate that GT crystallizes in the monoclinic crystal system. Various diffracting planes of the grown crystal were identified from ...
The structure of N,N'-bis(2-hydroxybenzylidene)-2,2-dimethyl-1,3-propanediamine, C19H22N2O2, has been studied at low temperature (120K) by means of single-crystal X-ray diffraction. Solving the structure shows an orthorhombic unit cell, with P212121 space group, Z = 4, a = 6.1046 (4) Å, b = 15.8349 (11)</e...
single crystal zno microrods are deposited on the surface of zn plate through corrosion of zn plate by h2o2, which is a green neutral reagent and easy to transform to h2o and o2. the structure and morphology of the obtained zno microrods were characterized by x-ray diffraction (xrd), scanning electron microscopy (sem), transmission electron microscopy (tem) and electron diffraction. a thermodyn...
