unsolvated 3. All halogens participate in halogenbonding, forming C–X···NC(M) halogen bonds and in one case a C–Br···O halogenbond (in 10·4H2O). The halogenbond distances are shorter than the corresponding sum of van der Waals radii, and stronger interactions are formed by iodine than bromine (I···N 2.789(7)–3.116(7), RIN 0.790–0.883; Br···N 2.884(3)–3.166(2), RBrN 0.848–0.931). Longer halogen bonds are
