Abstract

Three-spin magnetic cluster consists of manganese(II) and ortho-carboranyl biradical OCB-BNN have been synthesized and characterized as the first example of the carborane containing paramagnetic complex. The crystal structure of discrete 1:1 complex Mn(hfac)₂·OCB-BNN was unambiguously determined. In the crystal structure, OCB-BNN behaves as the molecular tweezers that bind to manganese(II) ion. The strong antiferromagnetic interaction (J/k_B = -181(2) K) was found between nitronyl nitroxides and manganese(II) ion.
