TitleExperimental charge density distribution in potassium azide by diffraction methods.
AuthorsStevens, E.D.
ReferenceActa Crystallographica A (1977) 33, 580-584
Link XRef SCOPUS SCIRUS Google
CompoundK1 N3 - Potassium azide [AX3] [tI16] [h c a] []
Cell6.1188(6), 6.1188(6), 7.1015(10), 90., 90., 90.
I4/MCM (140) V=265.88
RemarksR=0.007000 : ESC PDF =48-1276 :
Calculated density unusual but tolerable.
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.
