New crystal structures of (a)–(d) anhydrous and (e)–(h) hydrated forms of N-heterocyclic aromatics 1–(11). (i)–(k) Water molecules organize into (i) one-dimensional infinite chains (C2) in 6·2H2O and 11·2H2O, (j) discrete rings (R4) in 7·4H2O, and (k) pentagonal (T5(2)) and hexagonal infinite tapes (T6(1)) in 11·3H2O.
