The title polymers PNiPzS4 and PCuPzS4 were synthesized by reaction of phthalonitrile and 2,3,5,6-tetracyano-1,4-dithiin with corresponding metal salt.Their structures and properties were characterized by associating the experimental results with MO and CI calculations of the dinier molecule as model polymer in the ZJNDO method.It has been found that the PNiPzS4 (or PCuPzS4) shows the semiconductivity at T<253 K (or 260 K) and T>278 K (or 286 K) and the conductivity increase with a hoist of temperature at 253 K (or 260 K) 278 K (or 286 K) and the conductivity increase with The conductivity 298K of the PNiPzS4 and PCuPzS4 under pressure 13.73 MPa is 1.56 x 10-4 and 9.33 x 10-5 S / cm (or 260 K)
