# 4. TEXT


_publ_section_abstract

;
The crystal of the title Schiff base compound, C~20~H~18~ClN~3~O~3~.H~2~O,
was twinned by a 2-fold rotation about (100). The asymmetric unit contains
two crystallographically independent molecules with similar conformations
with respect to its bond sequence, and two water molecules. The C\\db N-N
angle of 115.7(6) and 116.2(6) \% are significantly smaller than the ideal
value of 120 \% expected for sp^2^-hybridized N atoms and the dihedral
angles between the benzene ring and quinoline ring system in the two
molecules are 52.5(7) and 53.9(7) \%. The organic molecules aggregate via
C-Cl...\p and \p...\p interactions [centroid-centroid distances
in the range of 3.696(5)-3.892(5) \%A] as parallel sheets array, and
these parallel sheets are further linked by uncoordinated water
molecules of N-H...O and O-H...O hydrogen bonds and weak C-H...O
interactions into a supramolecular two dimensional network.
