Abstract A new 2 $$\frac{1}{2}$$ -octahedral sheet silicate, NaMg2.5 Si4O10 (OH)2, has been synthesized from oxide mixtures in the temperature range 500–600°C at pressures between 1 and 5 kb. The lattice parameters are a 0 = 5.298 Å, b 0 = 9.047 Å, c 0 = 9.479 Å and ß=99.55°. X-ray data are given in the text. At temperatures above 605° C/1 kb and 630° C/5 kb, it decomposes to magnesiorichterite plus quartz.
