INVESTIGATION OF THE STRUCTURE OF AMMONIUM URANYL CUPFERRATE NH$sub 4$ UO$sub 2$(C$sub 6$H$sub 5$N$sub 2$O$sub 2$)$sub 3$

The ammonium uranyl cupferrate group has been shown to be primitive cubic with four molecules per unit cell, the locations of the carbon, nitrogen, and oxygen atoms in this structure were investigated. (J.R.D.)
