2-(1 H-1,2,3-Benzotriazol-1-ylmeth­yl)-1-(2,4-dichloro­benzo­yl)ethyl nicotinate monohydrate.

The molecules of the title compound, C21H14Cl2N4O3H2O, are linked into dimers by C—H… O hydrogen bonds and are linked into chains along the b axis by C—H…O and O—H…N hydrogen bonds involving the solvent water molecule. The packing is further stabilized by π-π interactions. [ABSTRACT FROM AUTHOR]
