“…Comprehensive study of the quasi-ternary system Ag 2 SÀCdSÀGa 2 S 3 reveals AgCd 2-GaS 4 as the only quaternary compound forming in this system [2]. This compound crystallizes in the orthorhombic symmetry, space group Pmn2 1 , with lattice parameters a ¼ 813.95 (9), b ¼ 693.94 (8) and c ¼ 660.14(7) pm and can be described as a superstructure of wurtzite [1,3]. The AgCd 2 GaS 4 is a semiconductor with n-type conductivity and energy gap E g ¼ 2.15 eV at 300 K [4].…”

“…The formation of a continuous solid solution AgCd 2 Ga(S 1Àx Se x ) 4 , x ¼ 0-1, has been demonstrated in a separate experiment [6,7]. The substitution in cation sublattice of the basic framework is also possible, and the solid solutions Ag 1Àx Cu x Cd 2 GaS 4 , x ¼ 0-0.34, and AgCd 2 Ga 1Àx In x S 4 , x ¼ 0-0.12, have been studied recently [8]. So, AgCd 2 GaS 4 crystal is a representative of a wide family of compounds the physical properties of which can be tuned via chemical composition variation.…”

“…When x = 2/3, is possible to find the family of compounds I-II 2 -III-VI 4 . Proof of the formation of these types of compounds can be found in the recent literature [2][3][4][5][6][7][8][9]. These phases fulfill the rules of adamantane compound formation [1] and belong to the two possible normal compound families of fourth derivatives of the II-VI binary semiconductors with three types of cations, the other family being I 2 -II-IV-VI 4 [10].…”

“…On the other hand, for materials with composition I-II 2 -III-VI 4 , some authors have reported structural studies for silver phases of the type AgCd 2 GaS 4 [3], AgCd 2 GaSe 4 [4], and the related systems Ag 1−x Cu x Cd 2 GaS 4 and AgCd 2 Ga 1−x In x S 4 [6], and AgCd 2−x Mn x GaS 4 [7]. All these phases crystallize in the orthorhombic space group Pmn2 1 with structures related to the wurtzite derivative as in the I 2 -II-IV-VI 4 family.…”
