Diaqua(2,2'-bipyridine-5,5'-dicarboxylato-
2N,N')(ethylenediamine-
2N,N')copper(II) 2.5-hydrate
In the molecule of the title compound, [Cu(C12H6N2O4)(C2H8N2)(H2O)2]·2.5H2O, the CuII atom is six-coordinated in a distorted octahedral configuration by two N atoms from a 2,2'-bipyridine-5,5'-dicarboxylate anion, two N atoms from ethylenediamine and two O atoms from two water molecules. There are also two and a half water molecules in the asymmetric unit. The planar five-membered ring is nearly coplanar with the adjacent pyridine rings, while the other five-membered ring adopts a twisted conformation, probably due to hydrogen bonding. In the crystal structure, intra- and intermolecular N-H
O and O-H
O hydrogen bonds link the molecules.
For the preparation of the title compound, ethylenediamine (0.15 g, 2.50 mmol)
was added to a suspension of 2,2'-bipyridine-5,5'-dicarboxylic acid (0.21 g,
0.83 mmol) in water (10 ml) and the resulting colorless solution was added to
CuCl2.2H2O (0.14 g, 0.83 mmol) in water (10 ml). The resulting blue
solution was stirred at 323 K for 15 min, and then was left to evaporate
slowly at room temperature. After one week, blue plate crystals of the title
compound were isolated (yield; 0.26 g, 70.01%, m.p. 488 K).
H3A, H3B, H4B, H4C (for NH2) and H5B, H5C, H6A, H6B, H7A, H7B, H8B, H9B, H9C
(for H2O) atoms were located in difference syntheses and refined
isotropically
[N—H = 0.85 (4)–0.89 (4) Å and Uiso(H) = 0.035 (8)–0.043 (9) Å2;
O—H = 0.72 (5)–0.97 (6) Å and Uiso(H) = 0.041 (10)–0.11 (2) Å2].
The remaining H atoms were positioned geometrically, with C—H = 0.93 and
0.97 Å for aromatic and methylene H, respectively, and constrained to ride
on their parent atoms with Uiso(H) = 1.2Ueq(C).

Special details top
Geometry. All e.s.d.'s (except the e.s.d. in the dihedral angle between two l.s.
planes) are estimated using the full covariance matrix. The cell e.s.d.'s
are taken into account individually in the estimation of e.s.d.'s in
distances, angles and torsion angles; correlations between e.s.d.'s in
cell parameters are only used when they are defined by crystal symmetry.
An approximate (isotropic) treatment of cell e.s.d.'s is used for
estimating e.s.d.'s involving l.s. planes. |
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. |

2,2'-Bipyridine-5,5'-dicarboxylic acid (BPDCH2) is a good bridging ligand, and numerous complexes with BPDCH2 anions have been prepared, such as that of cobalt (Min et al., 2002), platinum (Geary et al., 2003; Hafizovic et al., 2006), neodyminum (Schoknechta & Kempe, 2004), ruthenium and rhodium (Matthews et al., 2004) complexes. For further investigation of 2,2'-bipyridine-5,5'-dicarboxylic acid, we synthesized the title compound and report herein its crystal structure.
In the title compound, (Fig. 1), the CuII atom is six-coordinated in a distorted octahedral configuration by two N atoms from 2,2'-bipyridine-5,5'-dicarboxylate anion, two N atoms from ethylenediamine and two O atoms from two water molecules (Table 1). There are also two and a half water molecules in the asymmetric unit. Rings A (N1/C1/C2/C4–C6), B (N2/C7–C10/C12) and C (Cu1/N1/N2/C6/C7) are, of course, planar, and the dihedral angles between them are A/B = 1.43 (3)°, A/C = 2.09 (3)° and B/C = 2.45 (3)°. So, they are nearly coplanar, while ring D (Cu1/N3/N4/C13/C14) adopts twisted conformation, probably due to the hydrogen bondings.
In the crystal structure, intra- and intermolecular N—H···O and O—H···O hydrogen bonds (Table 2) link the molecules (Fig. 2), in which they may be effective in the stabilization of the structure.
