(a) Typical NH4H2PO4 crystal structure representation from a filtered data set. All hydrogen atoms were found and all the ADPs are reasonable after anisotropic refinement. (b), (c) Two typical NH4H2PO4 crystal structures obtained from unfiltered data sets. The refinement was unable to locate all the hydrogen atoms around the nitro­gen atom or to obtain reasonable displacement parameters for the nitro­gen atom. The dotted lines represent the hydrogen bond between the hydrogen atom and the oxygen atom. White – hydrogen; blue – nitro­gen; purple – phosphate; red – oxygen.
