The title compound was prepared following a published procedure (Padbury and Lindwall, 1945). Colorless single crystals suitable for X-ray diffraction were obtained by recrystallization from dimethylsulfoxide.
O-bound H atoms were located in a difference Fourier map and refined isotropically. The C-bound H atoms were placed in calculated positions, with C—H = 0.95 Å, and refined using a riding model, and with Uiso(H) value of 1.2Ueq(C).
Non-covalent interactions, such as hydrogen bonding, π-π stacking and C—H···π interactions, play a dominant role in supramolecular self-assembly (Casnati et al., 2003; Ghosh & Bharadwaj, 2004; Glidewell et al., 2005; Jennings et al., 2001). In order to further understand supramolecular self-assembly through non-covalent interactions, we have synthesized the title compound following a published procedure (Padbury and Lindwall, 1945). It is used as a material in the synthesis of organic metal compounds (You & Park, 2005; Kwon et al., 2005; Carlton & Molapisi, 2000; Smith et al., 1995).
Bond lengths and angles in (I) are normal. Compound (I) crystallizes in the triclinic space group P-1 with Z'=3. In (I), the three isoquinoline rings in the asymmetric unit are approximately planar, with maximum deviations of -0.014 (7) Å for atom C1 in N1/C1—C9 ring, 0.017 (6) Å for atom C2A in N1A/C1A—C9A ring and 0.022 (6) Å for atom C6B in N1B/C1B—C9B ring (Fig. 1). The torsion angles between the pyridine rings and carboxyl groups of three molecules in asymmetric unit are different. The N1—C1—C10—O1 torsion angle is -13.3 (2)°. However, the N1A—C1A—C10A—O1A and N1B—C1B—C10B—O1B are 36.17 (19) and -34.1 (2)°, respectively. The crystal packing is stabilized by O—H···N hydrogen bonds (Table 1).

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. |

Non-covalent interactions, such as hydrogen bonding, π-π stacking and C—H···π interactions, play a dominant role in supramolecular self-assembly (Casnati et al., 2003; Ghosh & Bharadwaj, 2004; Glidewell et al., 2005; Jennings et al., 2001). In order to further understand supramolecular self-assembly through non-covalent interactions, we have synthesized the title compound following a published procedure (Padbury and Lindwall, 1945). It is used as a material in the synthesis of organic metal compounds (You & Park, 2005; Kwon et al., 2005; Carlton & Molapisi, 2000; Smith et al., 1995).
Bond lengths and angles in (I) are normal. Compound (I) crystallizes in the triclinic space group P-1 with Z'=3. In (I), the three isoquinoline rings in the asymmetric unit are approximately planar, with maximum deviations of -0.014 (7) Å for atom C1 in N1/C1—C9 ring, 0.017 (6) Å for atom C2A in N1A/C1A—C9A ring and 0.022 (6) Å for atom C6B in N1B/C1B—C9B ring (Fig. 1). The torsion angles between the pyridine rings and carboxyl groups of three molecules in asymmetric unit are different. The N1—C1—C10—O1 torsion angle is -13.3 (2)°. However, the N1A—C1A—C10A—O1A and N1B—C1B—C10B—O1B are 36.17 (19) and -34.1 (2)°, respectively. The crystal packing is stabilized by O—H···N hydrogen bonds (Table 1).
