The redetermination of the crystal structures of Cu2CdSiS4 and Cu2HgSnS4 confirms the previously reported structure types and yields acceptable global instability index (G) values. Here it is demonstrated that accurate data collected on modern instrumentation should be used to reliably calculate bond valence sums and G values.

Stereochemically active lone pairs are an important non-bonding effect with significant implications on crystal structure and physical properties. This work reveals the highly repulsive nature of interactions between stereochemically active lone pairs, and shows how cooperative effects lead to stronger expression of stereochemically active lone pairs, affecting their impact on thermal conductivity.

The new quaternary thiosilicate, Li2PbSiS4 (dilithium lead silicon tetrasulfide), crystallizes in the noncentrosymmetric stannite structure type and belongs to a large family of severely compressed chalcopyrite-like compounds. The structure features a relatively regular SiS4 tetrahedron, a flattened LiS4 tetrahedron, and a distorted PbS8 dodecahedron. Electronic structure calculations using density functional theory indicate that the yellow compound is an indirect bandgap semiconductor.

Soluble tin(IV) chalcogenide complexes play a major role in solution processing synthesis of macroelectronic tin(IV) chalcogenide based devices, e.g. thin film transistors (TFTs) and the technological interesting photovoltaic material, Cu2ZnSnS4 (CZTS). The synthesis and study of new soluble thiostannate(IV) complexes without electronic impurity atoms and with low decomposition temperature are of key importance for the further development of tin(IV) chalcogenide based devices. We have from the same aqueous ammonium tin(IV) sulfide solution, synthesized and characterized four new crystal structures with different sized thiostannate(IV) complexes (i.e. monomeric [SnS4]4-, dimeric [Sn2S6]4-, pyramids of [Sn3S9]6- and the linear chain [SnS3]2-). Hirshfeld surface analysis for the anionic dimeric [Sn2S6]4- complex in (NH4)4Sn2S6·3H2O shows that water bound hydrogens interact equally well as the ammonium bound hydrogens with the anionic complex. The elongation of the terminal Sn-S bond depends only on the number of hydrogen atoms which interact with the sulfur atom (regardless of the hydrogen atom is bound in water molecules or in ammonium cations). We present the results for the application of the as-synthesized thiostannate(IV) crystals in solution processing of SnS2 thin films. Crystallographic and electron microscopic methods have established that all films are highly textured with the high mobility ab-plane parallel to the substrate surface. This is ideal for e.g. TFT devices where high mobility is required parallel to the substrate surface.

The structure of levyclaudite-(Sb), a member of the cylindrite mineral group, has been determined from a synthetic sample by single-crystal X-ray diffraction on the basis of the (3 + 2)-dimensional superspace approach.
