Abstract
Abstract1,8-bis(dimethylamino)naphthalene hydrobromide dihydrate, C14H19N2+Br · 2H2O, crystallizes in the space groupPnma witha=7.264(1),b=11.794(1),c=18.986 (2) Å,Z=4,Dm=1.34 g cm−3,DX=1350 kg cm−3. The structure was determined by Patterson and Fourier methods and refined to anR factor of 0.038. The 1,8-bis(dimethylamino)naphthalene cation has mirror symmetry, with the mirror plane passing along the C(9)-C(10) bond. The two N atoms are moved slightly out of the naphthalene plane. Theperi interactions are discussed in relation to aromaticity and to the N-C (ring) bond lengths. The structure contains channels of H bonds (Br− and water molecules) parallel toa which alternate with channels of cations in theb andc directions. One of the water molecules is disordered.
