A new hydrogen-bonded pseudo-dimer, [Mn(III)L1(CH(3)CH(2)OH)](2)(ClO(4)) (1) (L1 = N,N'-bis(2-hydroxy-1-naphthalidenato)-1,2-diaminopropane) has been synthesized and characterized by UV-vis, IR, elemental analysis and crystal structure analysis. The single crystal X-ray diffraction reveals that the structure affords an elongated octahedral MnN(2)O(4) coordination environment, geometry with the four donor atoms of the tetradentate Schiff base in the equatorial plane and with two ethanol molecule in axial positions with Mn-O = 2.265(2) and 2.266(2) Å.

The structures of the 1:1 proton-transfer compounds of 4,5-dichlorophthalic acid with 8-hydroxyquinoline, 8-aminoquinoline and quinoline-2-carboxylic acid (quinaldic acid), namely anhydrous 8-hydroxyquinolinium 2-carboxy-4,5-dichlorobenzoate, C(9)H(8)NO(+) x C(8)H(3)Cl(2)O(4)(-), (I), 8-aminoquinolinium 2-carboxy-4,5-dichlorobenzoate, C(9)H(9)N(2)(+) x C(8)H(3)Cl(2)O(4)(-), (II), and the adduct hydrate 2-carboxyquinolinium 2-carboxy-4,5-dichlorobenzoate quinolinium-2-carboxylate monohydrate, C(10)H(8)NO(2)(+) x C(8)H(3)Cl(2)O(4)(-) x C(10)H(7)NO(2) x H(2)O, (III), have been determined at 130 K. Compounds (I) and (II) are isomorphous and all three compounds have one-dimensional hydrogen-bonded chain structures, formed in (I) through O-H..

The structure of the title adduct compound, C(10)H(8)NO(2) (+)·C(6)H(2)N(3)O(9)S(-)·C(10)H(7)NO(2), from the reaction of 2,4,6-trinitro-benzene-sulfonic acid (picrylsulfonic acid) with quinoline-2-carboxylic acid (quinaldic acid) in 2-propanol-water, has been determined at 130 (2) K. The cation and the adduct species form a twisted cyclic hydrogen-bonded R(2) (2)(10) pseudo-dimer which is extended into a one-dimensional chain structure through short head-to-tail carboxylic acid O-H⋯O(carbox-yl) associations [O⋯O = 2.4711 (19) Å].

The title compounds, a hydrogen-bonded linear chain, [Mn(C18H18N2O4)(H2O)2]ClO4, (I), a hydrogen-bonded pseudo-dimer, [Mn(C16H10Cl4N2O2)(CH4O)(H2O)]ClO4, (II), and a dimer, [Mn2(C18H18N2O4)2(CH4O)2](ClO4)2, (III), respectively, have been structurally characterized. The three complexes are completely different in their structural features, despite identical counter-anions and only slight modification of the substituents in the ligands. Complex (I) affords an elongated octahedral coordination environment, with axial Mn-O(water) distances of 2.
