Infrared and Raman spectra of magnesium ammonium phosphate hexahydrate (struvite) and its isomorphous analogues. IV. FTIR spectra of protiated and partially deuterated nickel ammonium phosphate hexahydrate and nickel potassium phosphate hexahydrate

Effect of Amino Acids on Magnesium Ammonium Phosphate Hexahydrate (Struvite) Crystallization

Theoretical investigations of the optical spectra and EPR parameters for VO in Zinc Potassium Phosphate Hexahydrate

The optical spectrum band positions and EPR parameters (g factors g//, g⊥ and hyperfine structure constants A// and A⊥) for VO 2+ ions in zinc potassium phosphate hexahydrate are theoretically studied from the complete diagonalization (of energy matrix) method (CDM). In the calculation, the contributions to the EPR parameters from the s-and p-orbitals as well as the spin-orbit coupling coeffici...

Temperature Dependence Studies of 3 CI NQR Frequencies in Magnesium and Nickel Hexachlorotellurate(IV) Hexahydrates and Nickel Hexachloroiridate(IV) Hexahydrate*

The C1 NQR frequencies in MgTeCl6 • 6 H 2 0 , NiTeCl6 • 6 H 2 0 , and NiIrCl6 • 6 H 2 0 have been determined at various temperatures. These compounds form rhombohedral crystals with the space group R3, showing a single resonance line. The C1 NQR frequencies of the Te(IV) complexes exhibit an unusual positive temperature coefficient. The deuterated analogs of the Te(IV) complexes show a small fr...

Preparation of Nickel Ferrite from thermolysis of Nickel Hexa(Formato)-Ferrate(III)Hexahydrate

Thermal decomposition of nickel hexa(format0) fetrate(DQ decahydrate i.e. Ni3ve(HC00)s]2. 10H,O has been studied upto 913 K in static air atmosphere employing TG,DTG,DTApSC,XRD$!SR, Mossbauer and f i r e d spectroscopic techniques. Dehydration occurs in two stages in the temperature range of 348-423 K. Immediately &r the removal of the last water molecule, the anhydrous complex undergoes decomp...

Cadmium sulfite hexahydrate revisited

The present structural revision of the title compound, tetra-cadmium tetra-sulfite hexa-hydrate, [Cd(4)(SO(3))(4)(H(2)O)(5)]·H(2)O, is a low-temperature upgrade (T = 100 K and R = 0.017) of the original room-temperature structure reported by Kiers & Vos [Cryst. Struct. Commun. (1978). 7, 399-403; T = 293 K and R = 0.080). The compound is a three-dimensional polymer with four independent cadmium...
