N2 - Covalent bond tables are used to generate hydrogen-bond pattern designator symbols for the crystallographically characterized title compounds. 2-(Pyrazol-1-yl)ethyl-ammon-ium chloride, C5H10N 3 +·Cl-, (I), has three unique, strong, charge-assisted hydrogen bonds of the types N - H⋯Cl and N - H⋯N that form unary through ternary levels of graph-set inter-actions. Diaquadichloridobis(2-hydroxy-ethyl-ammonium)-cobalt(II) dichloride, [CoCl 2(C2H8NO)2(H2O) 2]Cl2, (II), forms five unique charge-assisted hydrogen bonds of the types O - H⋯Cl and N - H⋯Cl. These form graph-set patterns up to the quinary level. The Co complex in (II) resides at a crystallographic inversion center; thus the number of hydrogen bonds to consider doubles due to their G-equivalence, and the handling of such a case is demonstrated.
