{[Cu2(bpdado)2(H2O)2].H2O}n: a 1D nanotubular coordination polymer with wall made of edge-sharing hexagons, where bpdado = 2,2'-bipyridine-3,3'-dicarboxylate-1,1'-dioxide.

Utilizing 2,2'-bipyridine-3,3'-dicarboxylate-1,1'-dioxide and Cu2+ ions produces an antiferromagnetic, 1D nanotubular coordination polymer with its wall composed of edge-sharing hexagons, topologically similar to carbon nanotube.
