The crystal structure of the ordered vacancy compound (OVC) Cu 3 In 7 Te 12 is analyzed using powder X-ray diffraction data. It is found that this OVC crystallizes with a chalcopyrite-related structure, in the tetragonal space group P 4 2c (Nº 112), with unit cell parameters and volume a = 6.1720(2) Å, c = 12.3597(8) Å, and V = 470.83(4) Å 3. The Rietveld refinement of 28 instrumental and structural parameters led to R p = 9.27 %, R wp = 10.30 %, R exp = 6.95% and S = 1.48, for 4501 step intensities and 130 independent reflections, respectively. This compound is isostructural with Cu 3 In 7 Se 12 , and has a defect adamantane structure.

“…Bond distances in Table II show a Cu-Te bond length of 2.639(1) Å, In-Te of 2.768(1) Å and Nb-Te of 2.756(1) Å. These lengths compare well to those found for the related ternary adamantane structures: CuInTe 2 [23], CuNbTe 2 [44], Cu 3 NbTe 4 [45], AgIn 5 Te 8 [46], AgInTe 2 [47], Cu 3 In 5 Te 9 [48], Cu 3 In 7 Te 12 [49], and the quaternaries: CuTa 2 InTe 4 [50], CuCo 2 InTe 4 and CuNi 2 InTe 4 [51], and CuFeInTe 3 [52].…”

The quaternary alloy (CuIn)2NbTe5 was synthesized by solid-state reaction using the melt and annealing technique. The thermal analysis shows that this compound melts at 1026 K. The present alloy is isotypic with Cu2FeIn2Se5 and crystallizes in the space group P2c (Nº 112), with unit cell parameters a = 6.1964(2) Å, c = 12.4761(4) Å, c/a = 2.01, V = 479.02(3) Å3. (CuIn)2NbTe5, belonging to the system (CuInSe2)1-x(FeSe)x with x= ⅓, is a new adamantane compound with a P-chalcopyrite structure. This structure is characterized by a double alternation of anions-cations layers according to the Te-Te : Nb-In-Nb-In : Cu-In-Cu-In : Te-Te sequence, along the 010 direction.

“…Therefore, both stannite and PMCA structures support almost identical electronic physics. As the stannite-type structure has been reported experimentally [9,[16][17][18][19][20], we present our calculation results on the stannite-type CuInM 2 A 4 (M=Mn, Fe, Co, Ni, A=S,Se,Te) in the following. Fig.1 (a) and (b) show the CuInCo 2 A 4 (A=S, Se, Te) stannite and PMCA crystal structures, in which each CoA 2 layer is constructed by vertex shared tetrahedra.…”

Predicting diamond-like Co-based chalcogenides as unconventional high temperature superconductors

We predict Co-based chalcogenides with a diamond-like structure can host unconventional high temperature superconductivity (high-Tc). The essential electronic physics in these materials stems from the Co layers with each layer being formed by vertex-shared CoA4 (A=S,Se,Te) tetrahedra complexes, a material genome proposed recently by us to host potential unconventional high-Tc close to a d 7 filling configuration in 3d transition metal compounds. We calculate the magnetic ground states of different transition metal compounds with this structure. It is found that (Mn,Fe,Co)-based compounds all have a G-type antiferromagnetic(AFM) insulating ground state while Ni-based compounds are paramagnetic metal. The AFM interaction is the largest in the Co-based compounds as the three t2g orbitals all strongly participate in AFM superexchange interactions. The abrupt quenching of the magnetism from the Co to Ni-based compounds is very similar to those from Fe to Co-based pnictides in which a C-type AFM state appears in the Fe-based ones but vanishes in the Co-based ones. This behavior can be considered as an electronic signature of the high-Tc gene. Upon doping, as we predicted before, this family of Co-based compounds favor a strong d-wave pairing superconducting state.
