A new hydrogen-bonded charge-transfer complex [Ni(Hpydt)2]TNAP: Synthesis, structure and electrical conductivity

Bis(2,3-pyridinedithiolate)nickel(II) complex gives a hydrogen-bonded charge-transfer (HBCT) complex with 11,11,12,12-tetracyanonaphtho-2,6-quinodimethane (TNAP), [Ni(Hpydt)2]TNAP. This is the first example of an HBCT complex composed of TNAP. The donor and acceptor components alternate within each stack. The ionicity of the each component is estimated to be ±1.0. The electrical resistivity of the complex at 298 K is 640 Ω cm and the activation energy of 137 meV.
