In the molecule of the title compound, [Cu(C10H8N2)-(C4H2O4)(H2O)]2H2O, the Cu(II) atom has elongated tetra-gonal pyramidal geometry, coordinated by one water O atom, two N atoms of the 2,20-bipyridine ligand and two O atoms of
the two carboxylate groups of the maleate dianion. The molecules are linked through hydrogen-bonding and –
stacking interactions, forming a two-dimensional supra-molecular structure.
Comment
Metal–organic coordination complexes containing the maleate ligand have been studied extensively due to their wide range of applications (Maruoka et al., 1993; Chen & Suslick, 1993; Hoskins & Robson, 1990; Kondoet al., 1997). Here, we report the crystal structure of one such complex, the title compound, (I).
The structure of (I) consists of discrete monomers. The CuII atom exhibits an elongated tetragonal pyramidal geometry, coordinated by one water O atom, two N atoms of the 2,20
-bipyridine ligand and two O atoms of the two carboxylate groups of the maleate dianion (Table 1, Fig. 1).
The Cu—O(maleate) and Cu—O(water) bonds (Table 1) are slightly longer than the corresponding ones [1.876 (6), 1.894 (6) and 2.150 (6) A˚ ] in [Cu(pz)2(male)(H2O)] -1.5H2O, (II), where pz and male are 3,5-dimethylpyrazole and the maleate anion, respectively (Chen et al., 2003). It is not possible to compare the Cu—O(water) bond in (I) with those [1.975 (2) and 2.414 (2) A˚ ] reported in {[Cu(4,40
In the crystal structure, the molecules are packed via hydrogen bonds (Fig. 2) between water molecules and the uncoordinated O(maleate) atoms of neighbouring molecules (Table 2), and – stacking interactions with centroid– centroid distances of 3.811 (3) and 3.974 (3) A˚ between the pyridine ring of the molecule at (x;y;z) and those at (2x, y, 2z) and (2x,y, 1z), respectively, forming a two-dimensional supramolecular structure.
Experimental
Cu(NO3)23H2O (0.241 g, 1.0 mmol) was added slowly to an aqueous solution of maleic acid (0.116 g, 1.0 mmol, 15 ml), and the reaction mixture was stirred for 1 h at 353 K. An ethanol solution (5 ml) of 2,20-bipyridine (0.156 g, 1.0 mmol) was then added with continuous
stirring. NaOH solution (0.1 mol/l) was added until a pH of 7 was obtained. After 1 h, the reaction mixture was cooled to room temperature and then filtered. Blue single crystals were obtained from the filtrate after two weeks (yield 139.9 mg, 36%, m.p. 525 K).

Refinement. Refinement of F2 against ALL reflections. The weighted R-factor wR and goodness of fit S are based on F2, conventional R-factors R are based on F, with F set to zero for negative F2. The threshold expression of F2 > σ(F2) is used
only for calculating R-factors(gt) etc. and is not relevant to the choice of reflections for refinement. R-factors based on F2
are statistically about twice as large as those based on F, and R- factors based on ALL data will be even larger.
