The new quaternary selenophosphate phases AMP{sub 2}Se{sub 6} (A=Cu, Ag and M=Bi, Sb) were synthesized by ceramic methods at 1023 K. These phases were characterized by powder X-ray diffraction (XRD), Fourier transform infrared spectroscopy (FTIR), energy dispersive X-ray analysis (EDX) and a.c. and d.c. electrical conductivity measurements. The phases all show values of electrical conductivity, {sigma}, of about 10{sup -4} {omega}{sup -1} cm{sup -1} at 303 K and photoconductive effect. The conductivity is nearly five orders of magnitude larger than that of related phases.
