Abstract

Bis(hexafluoroacetylacetonato)copper(II) Cu(hfac)2(=M) reacts with 5-bromo-1,3-phenylenebis(N-tert-butylaminoxyl) 1 to yield a complex formula [M3·12]. The X-ray crystal structure shows that it crystallizes in the space group P1, with a = 12.469(2) A, b = 15.278(2) A, c = 11.602(2) A, α = 104.59(1)°, β = 111.86(1)°, γ = 88.32(1)°, and Z = 1, and contains molecules -M-1-M-1-M-aligned in a polymeric chain (Scheme 1). The magnetic susceptibility measurements revealed a structural transition at ca. 48 K accompanied by a temperature hysteresis.
