The Synthesis and Crystal Structures of Two-Dimensional Coordination Polymers of Ph2P(O)−CH2CH2−P(O)Ph2 and Ph2P(O)−C5H3N−P(O)Ph2 with Praseodymium

Reactions of Pr(NO3)3 with Ph2P(O)−CH2CH2−P(O)Ph2 and Ph2P(O)−C5H3N−P(O)Ph2 yielded layered network coordination polymers with
bidentate ligands spanning the lanthanide atoms in a bridging
fashion. The praseodymium cations with “spacer” ligands form two-dimensional building blocks assembling into either square grid or
herringbone network.

Pr(NO3)3与Ph2P(O)−CH2CH2−P(O)Ph2以及Ph2P(O)−C5H3N−P(O)Ph2的反应生成了具有双齿配体的层状网络配位聚合物，这些配体以桥连方式跨越镧系原子。具有“间隔”配体的镨离子形成二维构建单元，这些单元组装成方形网格或人字型网络。
