Abstract

A new material tetrakis-µ3- (methoxo)(methanol)-pentakis(acetylacetonate)(tricuprum (II), neodymium (III)) methanol (I) was synthesized as [Cu3Nd(AA)5(OCH3)4CH3OH] ∙ CH3OH,  where HAA = H3C–C(O)–CH2–C(O)–CH3. Based on the data of elemental analysis and physical-chemical research methods, it was found that the obtained coordination complex (I) contains atoms of Copper (II) and Neodymium (III) in the ratio Cu:Nd = 3:1, and its composition corresponds to the gross formula: Cu3NdО16C31Н55. The measurement of electrical conductivity of the obtained material was performed in the compressed form. For the coordination complex (I), the number of valence electrons in one molecule was calculated to be 270; the mass of one molecule was calculated to be 163,65·10-20 кг; the total number of molecules in the volume of a cylindrical sample weighing 0.125 g and having volume of 17,74∙10-9 m3 was calculated to be 7,638·1013 молек.; and the total number of valence electrons as 20,6232·1015. In the temperature range of 303 – 423 K, the specific resistance of the compressed sample decreases from 2∙1012 to 5∙104 Ohm∙cm, which confirms that the isolated compound is a semiconductor with a band gap of 1,6125 еВ. The electrical conductivity properties of the coordination complex as a thermosensitive element were studied; for this purpose we used an experimental sample of compressed material with geometric dimensions of 1·10-3 m×0,5·10-3 m×0,5·10-3 m.
