Ca[Ag₂(SCN)₄]·2H₂O

Ca[Ag₂(SCN)₄]·2H₂O contains eight-membered Ag₄S₄ rings bonded together through shared atoms to form layers parallel to (100). The thio­cyanate groups link the layers to Ca–O chains running parallel to the c axis.

Pseudo-merohedrally twinned praseodymium hexa­cyano­ferrate(III) tetrahydrate

The title compound crystallizes with the cyano groups forming a regular octahedral arrangement around the Fe atom. The Pr atom is eight-coordinated by six N atoms and two symmetry-related water mol­ecules. The second (uncoordinated, symmetry independent) water mol­ecule forms a hydrogen-bonded network with N atoms.

β-Tl₂SO₄

The ambient-temperature form of Tl₂SO₄, β-Tl₂SO₄, is isostructural with β-K₂SO₄ and consists of isolated SO₄ tetrahedra linked by two non-equivalent Tl atoms, which present a low stereochemical activity of their 6s² pairs.

Dicerium orthosilicate selenide and dicerium orthosilicate telluride, Ce₂(SiO₄)Q (Q = Se or Te)

The crystal structures of two new quaternary compounds, viz. dicerium orthosilicate selenide and dicerium orthosilicate telluride, Ce₂(SiO₄)Q (Q = Se or Te), have been determined from single-crystal X-ray diffraction data. Each structure comprises infinite chains of SiO₄ tetrahedra separated by Ce and Q atoms. The site symmetries are Ce m and 2, Si 2 and Q m. The O atoms are in general positions.
