The title complex (4) was synthesized according to literature procedures. For the ligand synthesis, 2,6-pyridinedicarbonyl dichloride (1) (An et al., 2003) and L-histidine methyl ester dihydrochloride (2) (Ryono & Weller, 1987) were prepared by reacting SOCl2 with 2,6-pyridinedicarboxylic acid and L-histidine, respectively. Ligand (3) of the title complex was synthesized by coupling 1 and 2 (Moriuchi et al., 2001). Finally, 4 was synthesized at room temperature by adding a MeOH solution of (CH3COO)2Cu·H2O (0.066 g, 0.33 mmol) into a MeOH solution of 3 (0.155 g, 0.33 mmol) and stirring the blue solution formed for 70 h. After solvent removal in a vacuum, the complex was obtained as a blue powder (Kurosaki et al., 2001). Blue crystals of the title compound, suitable for X-ray analysis, were obtained from a saturated solution of MeOH–MeCN (2:1).
The crystal selected for the X-ray measurement at 173 K was mounted on a glass fibre using the oil drop method (Kottke & Stalke, 1993). H atoms were introduced in their calculated positions (X—H = 0.84, 0.88, 0.95, 0.98, 0.99, or 1.00 Å, Uiso=1.2 times the Ueq of the carrier atom and Uiso=1.5 times the Ueq of the carrier atom for methyl and OH H atoms) and were kept riding with fixed geometry with respect to their carrier atoms. No H atom positions were identified for the disordered methanol molecule.

The title complex with one and a half methanol solvates crystallized in P21212 space group having two independent half molecules in the asymmetric unit sitting on a crystallographic C2 symmetry axes. Cu1, N1, C3 atoms of the one molecule and Cu2, N5 and C14 of the other molecule lie on 2-fold axes. The methanol molecule O12—C201 with site occupation factor 0.5 is disordered about a 2-fold axis. The same complex in dihydrate form instead of methanol has been previously found to crystallize in the P43212 space group (Otsuka et al., 1996, Kurosaki et al., 2001). In both complexes, geometry around a five coordinated Cu(II) cation is a distorted square pyramid (Figure 1). The measured bond lengths and angles of the title complex agree well with the values obtained for the previously determined structure (Kurosaki et al., 2001) with one exception. The N1—Cu1—N4 angle of the title complex differs as much as 9.85° less from the corresponding angle of the previously determined complex. Several intermolecular hydrogen bonds stabilize the molecular packing of the title complex.
