Description / Table of Contents:
The transition of the “ordered” anti-PbCl2 lattice in the anti-PbFCl lattice: The ternary phases ABX of the alkaline earths with main group IV elements (A = Ca, Sr, Ba; B = Mg; X = Si, Ge, Sn, Pb)The compounds CaMgX, SrMgX and BaMgX (X = Si, Ge, Sn, Pb) were synthesized and their structures determined. CaMgX and SrMgX crystallize in the “ordered” Anti-PbCl2-type and are therefore related to the binary compounds Ca2X(X = Si, Ge, Sn, Pb), which form the Anti-PbCl2-type too. The phases BaMgX build up the Anti-PbFCl-structure. The relations of these two different structures are discussed in respect to the radii of the components.
Notes:
Die Verbindungen CaMgX, SrMgX und BaMgX (X = Si, Ge, Sn, Pb) wurden dargestellt und strukturell untersucht. Die Phasen CaMgX und SrMgX kristallisieren im „geordneten“ Anti-PbCl2-Typ und stehen damit strukturell in direktem Zusammenhang zu den im Anti-PbCl2-Gitter kristallisierenden binären Verbindungen Ca2X (X = Si, Ge, Sn, Pb). Die Phasen BaMgX bilden dagegen den Anti-PbFCl-Typ aus. Das unterschiedliche strukturelle Verhalten wird anhand von Radienkriterien diskutiert.
