The synthesis and crystal structures of two-dimensional coordination polymers of Ph2P(O)-CH2CH2-P(O)Ph-2 and Ph2P(O)-C5H3N-P(O)Ph-2 with praseodymium
Reactions of Pr(NO3)(3) with Ph2P(O)-CH2CH2-P(O)Ph-2 and Ph(2)p(O)C5H3N-P(O)Ph-2 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.
