CompoundB1 K2 Na1 P2 - Dipotassium sodium catena-diphosphidoborate [ABC2X2] [mS24] [i5 d b] []
Cell12.561(2), 5.0031(19), 12.092(2), 90., 120.94(1), 90.
C12/M1 (12) V=651.78
RemarksR=0.023000 : P =88-1834 :
The coordinates are those given in the paper but the atomic distances do not agree with those calculated during testing.The coordinates are probably correct.
