a new proton transfer compound, formulated as (hamp-6-pic)(hpyzd) ∙h2o (1), has been synthesized from the reaction of pyrazine-2,3-dicarboxylic acid (h2pyzd)  and 2-amino-6-methyl pyridine (amp-6-pic), in 1:1 molar ratio. extensive o−h×××o, n−h×××n and o−h×××o hydrogen bonds involving (hamp-6-pic)+ cation, (hpyzd)- anion and co-crystal water molecule٫ static electronic٫ and π…π stacking interac...

In the pharmaceutical industry, co-crystals are becoming increasingly valuable as crystalline solids that can offer altered/improved physical properties of an active pharmaceutical ingredient (API) without changing its chemical identity or biological activity. In order to identify new solid forms of diclofenac-an analgesic with extremely poor aqueous solubility for which few co-crystal structur...

Metallic nanowires (Au, Ag, Cu, Ni, Co, and Rh) with an average diameter of 40 nm and a length of 3-5 μm have been fabricated by electrodeposition in the pores of track-etched polycarbonate membranes. Structural characterizations by transmission electron microscopy (TEM) and electron diffraction showed that nanowires of Au, Ag, and Cu are single-crystalline with a preferred [111] orientation, w...

The preparation and characterization of the nBu4N+ salts of two bis-orotate(2-) complexes of cobalt, namely bis(tetra-n-butylammonium) diaquabis(2,4-dioxo-1,2,3,4-tetrahydropyrimidin-1-ide-6-carboxylato-κ2N1,O6)cobalt(II) 1.8-hydrate, (C16H36N)2[Co(C5H2N2O4)2(H2O)2]·1.8H2O, (1), and tetra-n-butylammonium (2,2'-bipyridine-κ2N,N')bis(2,4-dioxo-1,2,3,4-tetrahydropyrimidin-1-ide-6-carboxylato-κ2N1,...

A novel complex of cadmium (II) [CdL0.5(NO3)(H2O)](1), L= N,N-bis (O-hydroxyacetophenone) ethylene diamine, have been synthesized as single crystal and nano size. Compound 1 in nano size was obtained under sonochemical irradiation and has been characterized by IR, 1HNMR spectroscopy, X-ray powder diffraction (XRD) and scanni...

Abstract A series of five M(II) silylamide complexes [M{Me 2 Si(NPh) }( i Pr Im) ] (M=Cr, Mn, Fe, Co, Zn), Im=1,3‐diisopropylimidazoline‐2‐ylidene) were synthesized and characterized by spectroscopic methods single crystal X‐ray analyses. The Cr(II) complex [Cr{Me exhibits a distorted square planar coordination from chelating Me group two NHC ligands. In the case Co Zn derivatives mode is tetra...
