One-dimensional strands of trigonellinium constructed by intermolecular strong O-H center dot center dot center dot O and weak C-H center dot center dot center dot O hydrogen bonds in the crystal of partially oxidized Ni(dmit)(2) salt
The trigonellinium cations in the partially oxidized Ni(dmit)(2) complex salt 1 formed strong O-H center dot center dot center dot O hydrogenbridged dimers, and the dimers are held together by the weak C(sp(2) and sp(3))-H center dot center dot center dot O hydrogen bond to form 1D strands. Further assembly through weak C(sp(3))-H center dot center dot center dot O hydrogen bond and pi center dot center dot center dot pi interaction resulted in the formation of Ni(dmit)(2) column structure.
