Comprehensive computerized survey of the slice configurations of NH sub(4)H sub(2)PO sub(4) (ADP) type structures

A thorough analysis of the surface configurations of NH sub(4)H sub(2)PO sub(4) (ADP) at the atomic/molecular level has revealed a large number of PBCs and F-slices. The computational results of these relatively early applications may be called into question in so far as they arise from an incomplete set of theoretical data. This paper provides a complete and detailed account of the surface configurations and a reliable classification of the crystal forms of ADP type structures. It focuses on the topological-combinatorial features of ADP obtained from a network analysis. The obtained results apply without modification to KDPd as well as any other structure processing the same combinatorial properties as ADP.
