General Description

Rubidium chloride (~82~Rb) is a chemical compound consisting of a rubidium atom and a chlorine atom. It is a white crystalline solid with a high melting point and is highly soluble in water. Rubidium chloride is commonly used in medical research and in the study of cellular physiology, as it can be used to stimulate and modulate certain cellular pathways. It has also been investigated for its potential use in optical devices and as a catalyst in organic synthesis. Rubidium chloride is considered to have low toxicity and is generally regarded as safe for handling within laboratory settings.

With the aid of the chevenard thermobalance the authors have traced the pyrolysis curve of the following compounds of rubidium : chloride, perchlorate, sulphate, hexanitritocobaltate, hexachlorostannate, hexachloroplatinate; they have determined the ternperatures of commencement of dissociation of these substances, shown the different behaviour of the neutral and the acid sulphates, and demonstrated that the hexamtritocobaltate (colialtinitrite) cannot be employed for gravimetric analysis and the hexachlorostannate (stannichloride) requires a special method of preparation in order to give accurate results.

Study of the temperature effect on the process of rubidium hexachlorotellurite decomposition

Thermal dissociation of rubidium hexachlorotellurite in inert atmosphere (argon) and in atmosphere with air access was studied. The DTG and DTA curves for the process of rubidium hexachlorotellurite thermal dissociation in the argon atmosphere are given. Their character is defined by the behavior of TeCl4, which is liberated on the decomposition of samples.

Rb3LnCl6*2H2O (Ln=La-Nd): Preparation, Crystal Structure, and Thermal Behaviour

The compounds Rb3LnCl6*2H2O (Ln=La-Nd) were prepared from acetic acid aspowders. The prepartion from aqueous solutions does not yield the pure products because RbCl precipitates as first compound. The structure of R b3LaCl6*2H2O was determined by X-ray analysis of a single crystal obtained from aqueous solution. The compounds with Ln=La-Nd are isotypic. Theycrystallize hexagonally in the space group P63/M (Rb3LaCl6*2H2O: a=1220 .4(2) pm, c=1688.6(3) pm) with Z=6. Anionic trimeric units [Ln3Cl12(H2O)6](3-) are stacked along the c-axis over the corners of the unit cell. In the stacking frequency the units are rotated by 60° with respect to each other around the c-axis. The coordination number (C.N.) of Ln(3+) is 8, which is satisfied by four bridging and two terminal chloride ions and two water molecules. The coordination spheres of the three rubidium ions in the different atomic positions are composed differently, their C.N. are 9, 8(+1) and 6(+6). The thermal dehydration of the compounds occurs in one step. The hydrates decompose at ca. 100°C to formthe anhydrous compounds Rb2LnCl5 und RbCl since the anhydrous chlorides Rb3LnCl6 are thermodynamically stable above ca. 400°C only.
