| Kubische Cyanomercurate NR4MHg(CN)4 (R = Et, Pr; M = Li, Na, K, Cu) mit Alumosilikatstruktur On Cubic Cyanomercurates NR4MHg(CN)4 (R = Et, Pr; M = Li, Na, K, Cu) with Alumosilicate Type Structure  | | | | Abstract
| Quaternary Cyanomercurates N R 4"[M H g(C N)4]~ with R = Et, Pr; M = Li, Na, K, Cu, obtained by reactions of N R 4C N . MCN and H g(C N)2 in polar solvents, are dim orphous. The low temperature modifications are tetragonal with a space group 14, the high temperature forms are cubic with the space group F 43m . Reversible phase transitions were studied by DSC, Raman spectroscopy and X-ray diffraction. They are o f first order and of displacive character. The X-ray structure determ inations o f the cubic forms of N E t4M H g(C N)4 with M = Na, Li showed tetra hedral M (N C)4-and H g(C N)4-groups connected by linear M —N C —Hg bridges to give three-dimensional frameworks o f a cristobalite type structure and with cavaties, in which the N E t4+ cations are located. | | | |
