Compounds are expressed by general formula of A.sub.x BC.sub.2-y where
0.ltoreq.x.ltoreq.2 and 0.ltoreq.y<1, and have CdI2 analogous layer
structures; A-site is occupied by at least one element selected from the
group consisting of Li, Na, K, Rb, Cs, Mg, Ca, Sr, Ba, Ti, V, Cr, Mn, Fe,
Co, Ni, Cu, Zn, Zr, Nb, Mo, Ru, Rh, Pd, Ag, Cd, Hf, Ta, W, Re, Ir, Pt, Au,
Sc, rare earth elements containing Y, B, Al, Ga, In, Tl, Sn, Pb and Bi;
B-site is occupied by at least one element selected from the group
consisting of Ti, V, Cr, Zr, Nb, Mo, Hf, Ta, W, Ir, and Sn; C-site is
occupied by at least one element selected from the group consisting of S,
Se and Te; the compounds exhibit large figure of merit so as to be
preferable for thermoelectric generator/refrigerator.
