Solid state conversion of a double helix thallium() coordination polymer to a corrugated tape silver() polymer

We observed the solid state conversion of a nanostructured Tl I coordination polymer with a double helix chain structure, prepared by a sonochemical procedure, to a nanostructured corrugated tape silver( i ) polymer via the mechanochemical reaction of [Tl( 2 -dcpa)] n ( 1 ) [Hdcpa = 2,4-dichlorophen...

Description
Summary:We observed the solid state conversion of a nanostructured Tl I coordination polymer with a double helix chain structure, prepared by a sonochemical procedure, to a nanostructured corrugated tape silver( i ) polymer via the mechanochemical reaction of [Tl( 2 -dcpa)] n ( 1 ) [Hdcpa = 2,4-dichlorophenoxyacetic acid] with AgNO 3 . The internal packing of these two compounds looked similar and low-energy structural changes allowed the conversion to occur smoothly. The transformation was irreversible as a result of the formation of stronger AgO bonds (in 2 ) compared with the initial TlO bonds (in 1 ). There are weak interaction planes in the crystal packing of 1 , so the structure is not mechanically rigid, which allows Ag ions to penetrate the lattice and form stronger bonds. Irreversible solid-state conversion of Tl I coordination polymer with double helix chain structure to corrugated tape silver( i ) polymer has been observed upon mechanochemical reaction of [Tl( 2 -dcpa)] n ( 1 ) with AgNO 3 .
