The transition is both displacive and order-disorder involving mainly conformational changes of the organic chain [NH3(CH2)5NH3]2+ coupled with distortion of the TlCl6 octahedra. This behaviour and the crystal dynamics will be discussed and compared with those found in the literature for ...
The static magnetic and dynamic properties of the compound(NH3)2(CH2)3CoCl4are investigated in the temperature interval0.5–50K. It is shown that atTN=2.05Kthis compound undergoes a transition to a magnetically ordered antiferromagnet state. A distinctive feature of this compound is the presence ...
To a solution of compound1(313 mg, 1.04 mmol) in MeOH (6 mL) was added hydrazinemonohydrate (0.1 mL, 1.67 mmol) at 0°C.After being stirred at same temperature for 3h, the solvents were removed invacuo and the residue was re-dissolved into water (10 mL). The pH ofsolution was th...

The present article is devoted to the characterization of the structural phase transitions of the [CH3NH3][Co(COOH)3] (1) perovskite-like metal–organic compound through variable-temperature single-crystal neutron diffraction. At room temperature, compound 1 crystallizes in the orthorhombic space group...
AN INFRARED SPECTROSCOPIC STUDY OF THE STRUCTURAL PHASE-TRANSITION IN THE PEROVSKITE-TYPE LAYER COMPOUND [N-C16H33NH3]2COCL4 The solid-solid phase transitions in the perovskite-type layer compound [ n -C 16 H 33 NH 3 ] 2 CoCl 4 have been studied by infrared spectroscopy. A new p......
A molecule is a group of two or more atoms joined by chemical bonds, whereas a compound is a substance formed by the chemical bonding of more than one type of element that exists in a fixed proportion.
