 Title    Ein neues Carbonat mit Baylissit-Struktur: Rb2[M g(C 03)2(H 20 )4] A New Carbonate with Baylissite Structure: Rb2 [Mg(C0 3 )2(H 2 0 )4]  
 Abstract    The new complex carbonate Rb2[M g (C 0 3)2(HoC))4] crystallizes in the Baylissite-tvpe structure with a = 1130,4(3), b = 641,9(1), c = 703,3(2) pm, ß = 99,62(1)°, V EZ = 503,2(2), space group P2l/n (No. 14) and Z = 2. In comparison with the isostructural potassium compound the cell dimensions increase in b-and c-and decrease in ö-direction. This effect depends on the greater coordination number of Rb+ and the rigidity of strong hydrogen bonds. The carbonate anion exhibits significant deviations from D 3h-symmetry (C -O : 127,1(5)-130,2(5) pm, Z_ O -C -O : 117.9(4)-121,1(3)°).
