Addition of the bis(β-diketone) ligand L [L =
1,3-bis(3-phenyl-3-oxopropanoyl)benzene] to a suitable source of
M
III
ions (M = Ti, V, Mn, Fe) in a L:M = 3:2 ratio gives the
dinuclear products [M
2
L
3
], which have a
triple-helical structure.
将双(δ-二酮)
配体 L [L = 1,3-双(3-苯基-3-氧代丙酰)苯] 加入合适的 M III 离子源(M = Ti、V、Mn、Fe)中,L:M = 3:2,可得到具有三螺旋结构的双核产物 [M 2 L 3 ]。
