Single crystals of pentaerbium trinickel trialuminium tetragermanium were synthesized from the elements by arc-melting. The novel compound crystallizes in the space group Pmmn, e6b2a, with all nine crystallographically unique atoms in special positions of site symmetries m.. and mm2. This compound represents a new ordered variant of the NbCoB type. Its… (More)
Formation of bismuth-based high-T<sub>c</sub> superconducting ceramics 2212 and 2223 with partial replacement of Bi by p-elements of group III (Ga, In), IV (Ge, Sn, Pb) or V (Sb) was studied. XRPD, DTA/TG, SEM/EDX, SQUID, and VSM were used for phase identification, structural analysis, grain morphology studies, chemical analysis and magnetic measurements.
A single crystal of the title compound, the ternary silicide digadolinium trirhenium penta-silicide, Gd2Re3Si5, was isolated from an alloy of nominal composition Gd20Re30Si50 synthesized by arc melting and investigated by X-ray single-crystal diffraction. Its crystal structure belongs to the U2Mn3Si5 structure type. All atoms in the asymmetric lie on… (More)
The reaction of Se(2)Cl(2) with RhCl(3).4H(2)O at 100 degrees C gives dirhodium nonaselenium hexachloride Rh(2)Se(9)Cl(6). The structure exhibits the first Se(9) ring observed to date.
Single crystals of didysprosium heptanickel tritin were synthesized from the constituent elements by arc-melting. Two of the five Ni atoms are at general sites and all other atoms are at sites with either twofold or m symmetry. The structure contains 'DyNi(5)Sn' and 'DyNi(2)Sn(2)' fragments and represents a new member of the CaCu(5) series of intermetallics.
The crystal structure of Gd3Ni7Al14 (trigadolinium heptanickel tetradecaaluminide) belongs to a family of two-layer structures and can be described as an assembly of interpenetrating centred straight prisms. For the Ni atoms, trigonal prisms (Al4Gd2 and Al6) are observed, the Al atoms are inside tetragonal (Ni2Al2Gd4, Ni2Al4Gd2, Al4Gd4, Ni4Al4 and Al8) and… (More)
High-purity Tl(1223) ceramics have been produced by a reaction under high isostatic gas pressure (50 bar). A new method of synthesis consisting in a two-step reaction involving substantial melting at very high temperature (up to 1100 °C) produced well-shaped plate-like grains. An electrophoretic deposition (ED) technique then was used to produce uniform… (More)
