Abstract

A series of new layered polymers consisting of Ln[Ph2P(O)-CH2CH2-P(O)Ph2]1.5 monomeric units, where Ln = Pr(NO3)3, Nd(NO3)3, NdCl3, Sm(NO3)3, GdCl3, Dy(NO3)3, are synthesized and structurally characterized. The solvothermally prepared polymers exhibit either parquet-floor or brick-wall architecture, whereas the polymers from gel-diffusion reactions resemble honeycomb networks.

Abstract

It is shown that two phosphine oxide ligands, Ph2P(O)-CH2CH2-P(O)Ph2 and Ph2P(O)-C5H3N-P(O)Ph2, acts as bridging bidentate ligands and form two-dimensional coordination polymers in the reactions with Pr(NO3)(sub 3). Different experiments conducted by using different method including the solvothermal synthesis are presented.

Abstract

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. [ABSTRACT FROM AUTHOR]
