The use of derivatised salicylaldoximes in Mn chemistry has led to the isolation of a plethora of beautiful new SMMs ranging in nuclearity from three to eight and with spin ground states as large as S = 12-including a Mn6 complex with the largest energy barrier to magnetisation reversal yet reported. The deliberate chemically-induced structural distortion of the [Mn6] molecule allows the isolation of analogous family members displaying remarkably different magnetic properties and this in turn allows for a rare semi-quantitative magneto-structural correlation which enables prediction of the magnetic properties of new family members.
衍生化水杨醛肟在锰化学中的应用已导致分离出大量新颖的单分子磁体(SMMs),其核数范围从三到八,自旋基态高达S = 12,包括一种具有迄今报道的最大磁化反转能垒的Mn6配合物。[Mn6]分子经刻意的化学诱导结构畸变,使得能够分离出具有显著不同磁性质的类似家族成员,这反过来又实现了罕见的半定量磁结构关联,从而能够预测新家族成员的磁性质。
