The first coordination polymer containing a chiral cyclotriphosphazene ligand

The preparation and the single crystal X-ray structure of a new chiral ligand, 3,3,5,5-tetrapyridyloxy-1,1-{(R)-1,1′-dioxy-2,2′-binapthyl}cyclotriphosphazene (LR), is described. LR reacts with [Ag(MeCN)4]PF6 to produce the complex {[AgLR](PF6) · Et2O · 2MeCN}n, which was also characterised by X-ray crystallography. The topology of complex is a 1D coordination polymer that, in the crystalline structure, consists of two different infinite chains arranged in layers that are approximately orthogonal to each another.
