“…On the other hand, I – anions are so far only known in oxidobismuthates(III) such as ErBi 2 O 4 I, where substantial I – ··· M 3+ contacts ( M = Er and Bi) are avoided and ψ 1 ‐square pyramids [BiO 4 ] 5– with apical lone pairs share four common oxygen corners to build up anionic layers with the composition 2 ∞ {[BiO v 4/2 ] – }. The same structural motif discovered by Schmidt and Oppermann for ErBi 2 O 4 I is found for all tetragonal lanthanoid(III) halide oxidobismuthates(III) with the formula Ln Bi 2 O 4 X ( Ln = La – Nd, Sm – Lu; X = Cl – I) according to Schmidt, Oppermann, Binnewies et al First studies for the analogous chloride oxidoantimonates(III) revealed that SmSb 2 O 4 Cl crystallizes just like SmBi 2 O 4 Cl, although no lattice parameters or other structural data have been reported by Schmidt, Oppermann , and Binnewies in this particular article from 2001 . 18 years later we were able to elucidate the true nature of “SmSb 2 O 4 Cl” by X‐ray single‐crystal diffraction and electron‐probe microanalysis and found a not so surprising analogy for “SmSb 2 O 4 Br”.…”

“…A comparison of the molar volumes of the quaternary chlorides revealed 84.42 cm 3 ·mol –1 for “SmSb 2 O 4 Cl” and 81.43 cm 3 ·mol –1 for SmBi 2 O 4 Cl . For the isotypic bromide derivatives, 88.80 cm 3 ·mol –1 for the oxidoantimonate(III) and 84.59 cm 3 ·mol –1 for the oxidobismuthate(III) are found . Nevertheless, the crystal structure refinements did match with the samarium(III) oxidobismuthate(III) halides (Figure ).…”

“…So sind insbesondere die Verbindungen mit der Zusammensetzung Bi 2 SEO 4 X (SE = La±Lu, X = Cl, Br, I) [8] sowie davon abgeleitete Sto È chiometrien SE x Bi 6±x O 8 Cl 2 fu È r Nd, Eu, Gd mit x = 1,0; 2,0; 3,0; 4,0 [2], Bi 3±x La x O 4 Cl mit x = 0,75; 1,0; 1,5; 2,0 [3], Bi 1, 5 Die Bismutseltenerdoxidhalogenide weisen gegenu È ber vergleichbaren Bismutoxidhalogeniden eine wesentlich ho È here thermische Stabilita È t auf, wobei eine Variation der Seltenerdkomponente keinen signifikanten Einfluû auf die thermische Stabilita Èt zeigt. Der thermische Abbau der Verbindungen Bi 2 SEO 4 Cl [8] zeigt zwei deutlich voneinander getrennte Bereiche. Die Zersetzung verla È uft in einem ersten Schritt unter Bildung von Bismutseltenerdoxiden und einer Gasphase, deren wesentliche Species BiCl g ist.…”
