One-dimensional strands of trigonellinium constructed by intermolecular strong O-H⋯O and weak C-H⋯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···O hydrogen-bridged dimers, and the dimers are held together by the weak C(sp2 and sp3)–H···O hydrog...
