2,2'-Bipyridylamine (5.0 mg, 0.03 mol) dissolved in 90% (v/v) methanol–water solution (2 ml) was mixed with p-nitrobenzoic acid (4.9 mg, 0.03 mol), dissolved in the same solution (2 ml) for 5 min at room temperature. This was followed by the addition of CuCl2.2H2O (5.0 mg, 0.03 mol) dissolved in H2O (1 ml) and reacted for 15 min at room temperature. After several days, green prismatic crystals of (I) appeared from the mother liquor.
All H atoms were placed in idealized positions and treated as riding, with C—H = 0.93 Å and N—H = 0.86, and with Uiso(H) = 1.2Ueq(C,N).
As part of our studies of new therapeutic drugs, we have reported the structures of ternary Cu(II) complexes with the heterocyclic ligand 2,2'-bipyridylamine (bpa) and various carboxylate ligands, such as p-hydroxybenzenecarboxylate (p-HB) (Wang & Okabe, 2005), cyclobutane-1,1-dicarboxylate (Yodoshi, Mototsuji & Okabe, 2007), benzenecarboxylate (BA) (Okabe et al., 2007), and glycinate (Yodoshi, Odoko & Okabe, 2007). In this study, we describe the structure of the title Cu(II) complex, (I), containing bpa and 4-nitrobenzoate (p-NBA) and chloride anions.
The overall structure of (I) is similar to those of the ternary Cu(II) complexes with bpa and p-HB (Wang & Okabe, 2005) and BA (Okabe et al., 2007). The central Cu atom in (I) (Fig. 1) has a square pyramidal CuN2O2Cl geometry (Table 1), resulting from its coordination by two N atoms from the bpa molecule, two O atoms from the p-NBA anion and one Cl atom. The four basal atoms (N1, N2, O1 and O2) are neary coplanar and the Cu atom deviates from their least-squares plane towards the apical Cl atom by 0.3274 (1) Å. The O1—Cu1—O2 and N1—Cu1—N2 bite angles of 64.25 (7) and 94.71 (8) Å, respectively, are in the ranges normally observed for these complexes (Wang & Okabe, 2005; Okabe et al., 2007; Yodoshi, Mototsuji & Okabe, 2007; Yodoshi, Odoko & Okabe, 2007; Youngme et al., 2004). The Cu—Cl distance of 2.468 (3)Å is intermediate between the known values from 2.336 (2) to 2.733 (2) Å (Mao et al., 2004; Brophy et al., 1999). Such long Cu—Cl bonds are explained by the well known Jahn-Teller effect.
As shown in Fig. 2, the crystal structure is stabilized by N3—H9···Cl1i hydrogen bonds [i: 2 - x, -y, 1 - z] as well as by three kinds of π-π stacking interactions with the distances between the centroids of the aromatic rings being 3.531 (4) Å for Cg1(N1/C1—C5) and Cg3(N2/C6—C10) at (1 - x, -y, -z), 3.754 (4) Å for Cg2(N1/C5/N3/C6/N2/Cu1) and Cg2 at (1 - x, -y, -z), and 3.549 (4) Å for Cg4(C12—C17) and Cg2 at (-x, -y, -1 - z).

As part of our studies of new therapeutic drugs, we have reported the structures of ternary Cu(II) complexes with the heterocyclic ligand 2,2'-bipyridylamine (bpa) and various carboxylate ligands, such as p-hydroxybenzenecarboxylate (p-HB) (Wang & Okabe, 2005), cyclobutane-1,1-dicarboxylate (Yodoshi, Mototsuji & Okabe, 2007), benzenecarboxylate (BA) (Okabe et al., 2007), and glycinate (Yodoshi, Odoko & Okabe, 2007). In this study, we describe the structure of the title Cu(II) complex, (I), containing bpa and 4-nitrobenzoate (p-NBA) and chloride anions.
The overall structure of (I) is similar to those of the ternary Cu(II) complexes with bpa and p-HB (Wang & Okabe, 2005) and BA (Okabe et al., 2007). The central Cu atom in (I) (Fig. 1) has a square pyramidal CuN2O2Cl geometry (Table 1), resulting from its coordination by two N atoms from the bpa molecule, two O atoms from the p-NBA anion and one Cl atom. The four basal atoms (N1, N2, O1 and O2) are neary coplanar and the Cu atom deviates from their least-squares plane towards the apical Cl atom by 0.3274 (1) Å. The O1—Cu1—O2 and N1—Cu1—N2 bite angles of 64.25 (7) and 94.71 (8) Å, respectively, are in the ranges normally observed for these complexes (Wang & Okabe, 2005; Okabe et al., 2007; Yodoshi, Mototsuji & Okabe, 2007; Yodoshi, Odoko & Okabe, 2007; Youngme et al., 2004). The Cu—Cl distance of 2.468 (3)Å is intermediate between the known values from 2.336 (2) to 2.733 (2) Å (Mao et al., 2004; Brophy et al., 1999). Such long Cu—Cl bonds are explained by the well known Jahn-Teller effect.
As shown in Fig. 2, the crystal structure is stabilized by N3—H9···Cl1i hydrogen bonds [i: 2 - x, -y, 1 - z] as well as by three kinds of π-π stacking interactions with the distances between the centroids of the aromatic rings being 3.531 (4) Å for Cg1(N1/C1—C5) and Cg3(N2/C6—C10) at (1 - x, -y, -z), 3.754 (4) Å for Cg2(N1/C5/N3/C6/N2/Cu1) and Cg2 at (1 - x, -y, -z), and 3.549 (4) Å for Cg4(C12—C17) and Cg2 at (-x, -y, -1 - z).
