Large transparent crystals (up to 800 μm) of a hydroxy-sodium gallogermanate sodalite have been prepared at between
100 and 150 °C in aqueous sodium tetramethylammonium hydroxide solutions. Single-crystal structure analysis gave the expected
space group (<i>P</i>4̄3<i>n</i>) but an unexpectedly small unit cell (8.951 Å) in which the longer (Ga,Ge)−O bond lengths are compensated
by T−O−T bond angles of ∼110°. The crystals provide a readily made framework for structure studies of encapsulated chemical
species.
