Ni(tpt)(NO ) -A Three-Dimensional Network with the Exceptional (12,3) Topology: A Self-Entangled Single Net.

The shortest circuits in the three-dimensional network with (12,3) topology of solvated Ni(tpt)(NO ) pass through one another (see picture). This network based upon interlinked double helices occupies a unique position in the set of (n,3) nets. tpt=tri-4-pyridyl-1,3,5-triazine.
