Four benzothiazole–ketoiminate-based organoboron complexes were demonstrated to show aggregation-induced emission, a large Stokes shift and high quantum yield in the solid-state, which were rationalized through X-ray crystal analysis, and electronic structure calculations.

The new ternary stannide PrRuSn was synthesized from the elements via arc-melting. PrRuSn is isopointal to the orthorhombic TiNiSi-type structure, space group Pnma. The structure was characterized by X-ray powder and single crystal diffraction: a = 761.7(2), b = 483.9(2) and c = 730.3(3) pm, wR2 = 0.0386, 433 F2 values, 20 variables. The ruthenium and tin atoms in PrRuSn build up a three-dimensional [RuSn] polyanionic network with Ru-Sn distances in the range 268 - 274 pm. The praseodymium atoms fill channels within the polyanion. They bind to the network via short Pr-Ru distances of 301 and 302 pm. Electronic structure calculations on PrRuSn and isopointal PrPdSn underline these features and reveal strong T-Sn (T = Ru, Pd) interactions within both solid state structures.

A rare-earth-containing compound, ytterbium aluminium antimonide, Yb3AlSb3 (Ca3AlAs3-type structure), has been successfully synthesized within the Yb–Al–Sb system through flux methods. According to the Zintl formalism, this structure is nominally made up of (Yb2+)3[(Al1−)(1b – Sb2−)2(2b – Sb1−)], where 1b and 2b indicate 1-bonded and 2-bonded, respectively, and Al is treated as part of the covalent anionic network. The crystal structure features infinite corner-sharing AlSb4 tetrahedra, [AlSb2Sb2/2]6−, with Yb2+ cations residing between the tetrahedra to provide charge balance. Herein, the synthetic conditions, the crystal structure determined from single-crystal X-ray diffraction data, and electronic structure calculations are reported.
