Reversible liquid assisted mechanochemical conversion of sodium coordination polymer nanorods to organosilver coordination polymer nanosheets

Reversible solid-state structural transformation of sodium(I) coordination polymer nanorods, prepared by sonochemical procedure, to organosilver coordination polymer nanosheets has been observed upon liquid assisted mechanochemical reaction of compound [Na-2(1,5-nds)(H2O)(2)](n) (1), [1,5-H(2)nds = 1,5-naphthalenedisulfonic acid] with AgNO3. During this conversion, two coordinated H2O molecules were removed from 1 and substituted with two carbon atoms from 1,5-nds(2-) ligand in 2. Thus organosilver coordination polymer of 2 was formed during this conversion and distorted trigonal-bipyramidal coordination geometry in 1 with NaO5 coordination sphere was converted to distorted tetrahedral geometry in 2 (regarding the C=C group as one donor) with AgO3C2 coordination sphere.
