摘要: Abstract Bis(hexafluoroacetylacetonato)copper(II), Cu(hfac)2 (= M) reacts with 5-bromo-1,3-phenylenebis(N-tert-butylaminoxyl), 1 Br to yield a complex of formula [M 3·(1 Br)2]. The X-ray crystal structure shows that it crystallizes in the space group P2, = 12.469(2) A, b 15.278(2) c= 11.602(2) α 104.59(1)°;, β 111.86(1)°;, γ= 88.32(1)°;, and Z= 1. contains copper(II) trinuclear structure, M-1 Br-M-1 Br-M. magnetic susceptibility measurements revealed structural transition at ca. 48 K accompanied by temperature hystereisis.
