Tricalcium silicate Ca 30 [ Si 04 J : The monoclinic superstructure
Crystals, free from twinning, ofthe monoclinic phase oftricalcium silicate exhibiting superstructure reflections have been obtained. Crystal data are: a = 33.083(8), b = 7.027(2), e = 18.499(4) A, f3 = 94.12(2)°, Z = 36 x CaZ.89Mgo.ll0Si04, V = 4289 A3. The structure analysis was carried out using 3886 independent reflection intensities measured on a single-crystal diffractometer. The unit cell...
متن کاملRedetermination of Nd2Ti2O7: a non-centrosymmetric structure with perovskite-type slabs
Single crystals of dineodymium(III) dititanium(IV) hepta-oxide, Nd2Ti2O7, were synthesized by the flux method and found to belong to the family of compounds with perovskite-type structural motifs. The asymmetric unit contains four Nd, four Ti and 14 O-atom sites. The perovskite-type slabs are stacked parallel to (010) with a thickness corresponding to four corner-sharing TiO6 octa-hedra. The Nd...
متن کاملSpin-orbital superstructure in strained ferrimagnetic perovskite cobalt oxide.
We have investigated the Co-3d spin-orbital state in a thin film of perovskite LaCoO3 to clarify the origin of strain induced spontaneous magnetization (T(C)=94 K) by means of x-ray diffraction, optical spectroscopy, and magnetization measurements. A lattice distortion with the propagation vector (1/4 -1/4 1/4) and an anomalous activation of optical phonons coupled to Co-3d orbital are observed...
متن کاملSuperstructure of Mullite-type KAl9O14
Large whiskers of a new KAl9O14 polymorph with mullite-type structure were synthesized. The chemical composition of the crystals was confirmed by energy-dispersive X-ray spectroscopy, and the structure was determined using single-crystal X-ray diffraction. Nanosized twin domains and one-dimensional diffuse scattering were observed utilizing transmission electron microscopy. The compound crystal...
متن کاملElectrochemical fluorination of perovskite type BaFeO2.5.
Here we report on the first electrochemical fluorination exemplarily performed on perovskite type BaFeO2.5. A cell setup of the type BaFeO2.5 II La0.9Ba0.1F2.9 II MFx (with MFx being MgF2 and CeF3) was used to perform the reaction, charging the cell up to voltages of about 4 V. Formation of a compound of approximate composition BaFeO2.5F∼0.5 was observed, in agreement with diffraction studies o...
