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.
硝酸镨（Pr(NO3)3）与二苯基膦酰基 - 1,2 - 乙烷（Ph2P(O)-CH2CH2-P(O)Ph2）以及二苯基膦酰基 - 2 - 吡啶基（Ph2P(O)-C5H3N-P(O)Ph2）反应生成了层状网络配位聚合物，其中双齿配体以桥连方式跨越镧系原子。带有“间隔”配体的镨阳离子形成二维结构单元，组装成方形网格或人字形网络。
