| Abstract: | Na4K2Ge2O7 is monoclinic, space group P 21 (No. 4),a=6.010 (3),b=6.020 (3),c=29.26 (1) Å, γ=119.9 (1)° andZ=4. Its crystal structure has been determined from 1210 single crystal X-ray reflections and refined toR=0.114. The structure contains two independent Ge2O7 groups, the (GeOGe) angles of which are 128 and 132°. |
