Two new isostructural phosphine coordination materials, Ln-PCM-21 (Ln = Pr, Nd), have been obtained using a tris(p-carboxylated) methyltriphenylphosphonium ligand that is formally dianionic when triply deprotonated, allowing access to materials based on uncommon metal-to-ligand ratios. The polymers of the formula [Ln3(mptbc)4]X·solv (X = Cl(-), NO3(-)) are cationic and contain unusual, linear oxo-bridged Ln3 clusters. Magnetic susceptibility data for both the Pr and Nd analogues has been compared to models based on three contrasting approaches.
通过使用三（对羧基化）甲基三苯基鏻配体获得了两种新的同构磷化氢配位材料Ln-PCM-21（Ln = Pr，Nd），该配体在三重去质子化时形式上为双阴离子，从而能够获得基于不常见金属与配体比例的材料。式[Ln3(mptbc)4]X·solv（X = Cl(-)，NO3(-)）的聚合物是阳离子性的，并且包含不寻常的线性氧桥联Ln3簇。已将Pr和Nd类似物的磁化率数据与基于三种对比方法的模型进行了比较。
