Abstract：a new 3D supramolecular complex containing helical water chains , [ Mn( C19 H9 N3 O4 ) (H2O)4]· 7H2O (1) has been synthesized by utilizing a new ligand L [L =3,5-(4,5-diazafluoren-9-ylidene-amino) benzoic acid] and Mn(CH3COO)2· 4H2O in the routine method, which has been character-ized structurally by elemental analysis , IR spectroscopy and X -single crystal diffraction .Compound 1 crystalli-zes in space group P212121, with cell parameters a =0.99573 (8) nm, b=1.34347 (12) nm, c=2.06644 (18) nm.Compound 1 exhibits a 3D supramelocular structure constructed from novel helical water chains and [ Mn( C19 H9 N3 O4 ) ( H2 O) 4 ] building units via hydrogen bonding interactions .
