Structure, ordering, and bonding of half antiperovskites: PbNi3/2S and BiPd3/2S

Low-temperature route to shandite Ni3Pb2S2: A study of preparation via ethylene glycol reflux

“…All the diffraction peaks can be indexed to Ni 3 Pb 2 S 2 (JCPDS File No. 492070.0433 nm and c ¼ 14.196870.360l nm, which is in agreement with shandite-type structure with a space group of R 3m (Space group No.166) and the reported result[4]. It indicates the combination reaction of Ni and PbS, as illustrated in the equation 3Ni þ 2PbS !…”

“…But also because striking structures are observed in the mixed metal-rich chalcogenides, which form a wide variety of heterometallic bonds [2][3][4] ranging from 1D chains in Sc 14 M 3 Te 8 (M ¼ Ru, Os) [5], to 2D slabs in Ni 6 SnS 2 , Ni 9 Sn 2 S 2 [6] and 3D frameworks Ni 3 Pb 2 S 2 .…”

“…In our work, a reflux route was chosen because it was mild and efficient in various preparations [4,[12][13][14][15]. The reaction temperature was as low as 166 1C, which was the lowest temperature in the synthesis of Ni 3 Pb 2 S 2 so far as we know.…”

Low-field anomalous magnetic phase in the kagome-lattice shandite Co3Sn2S2

“…Co 3 Sn 2 S 2 consists of Co-Sn metallic layers, stacked along c-axis in the hexagonal setting of R3m structure, that are separated by Sn-S blocks [21][22][23][24][25][26] . In each layer, Co atoms are arranged in a 2D kagomé sublattice as shown in Fig.…”

Single crystal growth and characterization of kagomé-lattice shandites Co3Sn2−In S2

“…The shandites show a low dimensional crystal structure and fascinating electronic properties that have been studied extensively in recent decades [2][3][4][5]. The crystallographic and electronic structures of monoclinic parkerite (BiNi 3/2 S) and several shandites (MT 3/2 X), which are classified as ordered half antiperovskites, have been investigated by x-ray diffraction (XRD) and band structure calculations [6][7][8][9][10].
