Two possible choices for the polymer unit of XOJWUP, [Zn3(C7H4PO5)2(NH2CH2CH2NH2)2]n (H atoms omitted for clarity): at the top, the unit found by the algorithm reported herein; at the bottom the smaller unit chosen by CSD editors. Although unnecessarily large, the former arguably gives a clearer picture of the bonding. Some peripheral atoms in both representations are `link atoms', i.e. atoms of adjacent units of the polymer. |
