[Cu(men)2(BF4)2] (men = N-methyl-1,2-diaminoethane): Preparation, crystal structure, spectroscopic and magnetic properties

Popis výsledku v původním jazyce

Single crystals of [Cu(men)2(BF4)2] (men = N-methyl-1,2-diaminoethane) (1) were isolated from an aqueous-ethanolic system (Cu2+)-men-(BF4?). The crystal structure of 1 consists of [Cu(men)2(BF4)2] molecules. Copper ion exhibits usual distorted octahedralcoordination; there are two coordinated men ligands in the equatorial plane with Cu-N bonds of 2.0451(12) and 2.0035(12) ?, while the axial positions are occupied by fluorine atoms from BF4? anions with Cu-F bond of 2.5091(11) ?. The packing of the [Cu(men)2(BF4)2] molecules is governed by N-HF type hydrogen bonds. The measured ESR spectrum corroborated the presence of Jahn-Teller anisotropy of Cu(II). The magnetic studies in the temperature range 300-2 K reveal that 1 follows the Curie-Weiss law withparameters g = 2.1612(1) and théta = ?0.233(1) K suggesting the presence of weak antiferomagnetic interactions.
