Structural analysis of the nitrate complex of a thiophene-based azacryptand suggests that three nitrates are bridged with two bridgehead protons which play the topological role of two transition metal ions in a classical Werner type coordination complex bridging three anions.

the mössbauer spectra of nanoferrite materials such as ni0.25mn0.75fe2o4, co0.5mn0.5fe2o4 and ni0.4co0.6fe2o4 have been reported and the above materials were prepared by sol-gel combustion method using metal nitrates as source material and polyvinyl alcohol(pva) as agglomeration reducing agent. as the structural, thermal and magnetic properties (vsm) of the above ferrites have been published al...

Nitration of phenol and various 4-substituted phenols with Cu(NO3)2.3H2O, Cu(NO3)2.3H2O/SiO2, 9H2O and Cr(NO3)2. 9H2O in different anhydrous organic solvents are investigated. High selectivity ratio of para vs ortho isomers has been observed. Mono- and dinitro compounds f...

Mixed ligand complexes of transition metal ions such as Mn(II), Fe(III), Co(II), Ni(II), Cu(II) and Zn(II) have been synthesized using 4-(Benzeneazo)salicylaldehyde, 2-amino-4-nitrophenol and nitrates of respective metal ions. The synthesized complexes have been characterized with infra red (IR), electronic, and H-NMR Spectra, molar conductance and magnetic susceptibility measurements at room t...

Abstract: Nanocrystalline MgAl2O4 spinel powder was synthesized using metal nitrates and a polymer matrix-based composed of sucrose and polyvinyl alcohol (PVA). The precursor and the calcined powders were characterized by simultaneous thermal analysis (STA), X-ray diffraction (XRD), Fourier transform infrared spectroscopy (FT-IR), and scanning electron microscopy (SEM). According to XRD res...

The lanthanide oxide nitrates LnONO3 with Ln = Pr, Nd, and Sm-Yb were synthesised by thermal decomposition of hydrated lanthanide nitrates. The compounds were refined isotypically to YONO3 in the tetragonal space group P4/nmm and the structure is closely related to the PbFCl-type. Because of the orientational disorder of NO3− in this structure refinement a possible superstructure is discussed. ...

A new building block containing an imidazolium salt was synthesized and used for the construction of supramolecular networks with metal ions. We discovered the concomitant formation of the N-heterocyclic carbene-copper complex (CN = 2) in the self-assembly of imidazolium dicarboxylates and copper nitrates in N,N-dimethylformamide under heating. The proton in the 2 position of the imidazolium sa...
