“…However, most of the so obtained high-temperature phases contain only relatively simple anionic units, and the formation of larger aggregates like chains or rings have not been observed under these conditions. The second method is the hydro-(or solvo-) thermal synthesis [8]. In this case smaller units assemble to larger anionic aggregates of various structures.…”

Dedicated to Professor Hubert Schmidbaur on the occasion of his 75 th birthdayThe reactions of Zintl ions Sn 9 4− formed in ethylenediamine solutions of K 2 Cs 2 Sn 9 and Rb 4 Sn 9 with elemental tellurium have been investigated. Addition of elemental tellurium to the filtrates of these solutions leads -depending on the reaction conditions -to four different products: Compounds K 0.36 (1 [Sn 4 Te 12 ] (4). Compounds 1, 2 and 4 have been structurally characterized by single-crystal X-ray diffraction.

“…Recently, the chemical route for material preparation was preferred as an effective and convenient technique, with reduced energy and material requirements [13,14]. However, the hydrothermal route is one of the most widely used, owing to its economics and high degree of compositional control [15].…”

A series of Ni doped cobalt ferrite compounds with the formula Ni x Co 1−x Fe 2 O 4 where x=0, 0.2, 0.4, 0.6, 0.8, and 1.0 were prepared using a hydrothermal method and subsequently sintered/annealed at 600• C for 3 h. The influence of the Ni content on the lattice parameter, a, stretching vibration and the magnetization of specimens were subsequently studied. XRD and FTIR were used to investigate structure and composition variations. All samples were found to have a cubic spinel structure. SEM was used to study morphological variations. The results indicate that the average particle sizes are between 30-35 nm with a narrow size distribution along with nanocrystals forming of regular octahedrons. A decrease in the peak to peak line width and increase in resonance field with increasing Ni content were observed from ESR measurements. Based on ESR results, a core-shell type of formation was proposed where the core is made up of undoped CoFe 2 O 4 and the shell is Ni 2+ doped CoFe 2 O 4 .

Source of materialSingle crystals of (C 2 ,dried over Na/CaH 2 ,freshly distilled and degassed) were added to the reaction mixture which was then loaded into aT eflon-lined autoclave with an inner volumeof20mL(filling degree approx. 30%). The sealed autoclave was heated at 443 Kfor 7days before cooling down to room temperature. Air sensitive yellow needles of the target compound were isolated from the crystalline product, which also contained the unreacted selenium.The chemical composition of (Zn:Sb:Se =1:1:4) was confirmed by EDXS measurements. Experimental detailsThe positions of all protons attached to Cand Natoms were located from the difference Fourier map. ), 0.90 Å, and 0.86 Å(NH 2 )with U iso (H) =1.2 U eq (C or N).
