Although systematic absences and symmetry relations among reflections pointed to space group I4(1)22 (one molecule in the asymmetric unit), a direct methods solution could only be obtained in I(-)4 (two molecules in the asymmetric unit). Re...

Dodecylnicotinate bis-adducts of binuclear copper carboxylates, of the general formula Cu2(O2CC(n-1)H(2n-1))4(C5H4NCOOC12H25)2, were synthesized for n = 10, 12, 14, 16, 18 and 20, and their crystal structure, thermal behavior and magnetic p...
Structures and phase transitions of B-Ta2O5 and Z-Ta2O5: two high-pressure forms of Ta2O5 [0.03%]

Density functional theory-based calculations have been used to demonstrate that the aplanarity of CO3 groups in some carbonates such as dolomite, CaMg(CO3)2, aragonite, CaCO3, and norsethite, BaMg(CO3)2, is a ground-state property. This dis...

A new empirical relationship s = s0(R0 - lambda)3/(R - lambda)3 between bond distances and bond valences is proposed, where s is the bond valence for the bond distance R, s0 is the reference bond valence for the reference system with the re...
Ab initio structure determination and Rietveld refinement of a high-temperature phase of zirconium hydrogen phosphate and a new polymorph of zirconium pyrophosphate from in situ temperature-resolved powder diffraction data [0.03%]
