摘要：

K-6[Be4O(CO3)(6)]. 7 H2O has been prepared by dissolving freshly precipitated Be(OH)(2) in an aqueous KHCO3 solution. After enriching the title compound by extraction with ethanol the heptahydrate crystallizes from the organic phase (triklin, P (1) over bar (No. 2) with a=951,01(11), b=958,45(12), c=1601,7(2) pm, alpha=79,253(13)degrees, beta=78,943(12), gamma=65,119(12)degrees, V-EZ=1290,6(3).10(6) pm(3), Z=2). Thermal decomposition forms rhombohedral crystals of the anhydrous compound (trigonal-rhombohedric, R (3) over bar (No. 148) with a=1416,42(6), c=1704,5(1) pm, V-EZ=2961,4(3).10(6) pm(3), Z=6).
