There have been a number of reports on coordination compounds with Schiff-base ligands because of their diverse coordination modes and relevance to the biological active metal center. [1][2][3][4][5][6] Recently, we isolated a nickel(II) complex with a compartmenttype Schiff-base ligand containing a pyrrole group, 1,3-bis(pyrrole-2-methylydeneamino)-2-propanol (H3bpmp), [Ni(Hbpmp)]·0.5CH3OH, which was thought to be interesting compared with a biologically important imidazole derivative ligand.7 X-ray crystallographic work revealed a mononuclear structure with a square-planar arrangement of the nickel(II) ion with a partially deprotonated Schiff-base ligand. In this study, we prepared a copper(II) complex with H3bpmp, [Cu(Hbpmp)]· 0.5C2H5OH ( Fig. 1), in order to compare the crystal structure with that of the nickel(II) complex. So far, a similar copper(II) complex was reported as [Cu (Hbpmp) and wR2 (all data) values are 0.0320 and 0.0991, respectively, for all 3378 independent reflections. The complex is essentially a square-planar copper(II) complex with partially deprotonated Hbpmp 2-; this mononuclear unit is loosely connected by the axial semicoordination of the alcohol group of the Hbpmp 2-ligand of the neighboring mononuclear unit to form a dinuclear assembly. The temperature dependence of the magnetic susceptibility (4.5 -300 K) follows the Curie-Weiss law with θ = -1.2 K, showing a weak antiferromagnetic interaction between the copper(II) ions, consistent with the crystal structure.
