The complete crystal structure of C 10 H 19 NH 2 , HCl,1½, H 2 O has been established by three‐dimensional methods (P ATTERSON synthesis, B UERGER 's minimum function, F OURIER syntheses and refinement by least square methods). The carbon skeleton of the molecule has almost the symmetry C 2h − 2/m . Its conformation and dimensions (bond lengths and angles) are almost identical with those of 1,6‐ trans (and cis )‐di‐aminocyclodecane dihydrochloride. It is significantly different from the («crown») Y‐model, assumed earlier Hydrogen bonds between the ring, the HC1 and H 2 O molecules build up a double layer // (100); these layers are only connected by VAN DER W AALS ' forces, and not by direct strong bonds.
