Cover illustration: The two types of ladder formed by ammonium carboxylate salts. Type II (left) has repeating R(10) rings, whereas type III (right) has alternating R(8) and R(12) rings. The three hydrogen bonds from the -NH3+ cation consist of two legs and one rung. See Lemmerer [Acta Cryst. (2011), C67, o92-o99]. |
