摘要

The title compound, catena-poly[[[diaqua(methanol-kappa O)copper(II)]-mu-N-(4-methylpyrimidin-2-yl-kappa N-1)pyrazin-2-amine-kappa N-2(1):N-4] [[aqua(aqua/methanol-kappa O)(perchlorato-kappa O) copper(II)]-mu-N-(4-methylpyrimidin-2-yl-kappa N-1)pyrazin-2-amine-kappa N-2(1):N-4] tris(perchlorate) methanol monosolvate 1.419-hydrate], {[Cu(C9H9N5)(CH3OH)(H2O)(2)][Cu(C9H9N5)(ClO4)(CH3OH)(0.581)(H2O)(1.419)](ClO4)(3)center dot CH3OH center dot 1.419H(2)O}(n), is a one-dimensional straight-chain polymer of N-(4-methylpyrimidin-2-yl)pyrazin-2-amine (L) with Cu(ClO4)(2). The complex consists of two crystallographically independent one-dimensional chains in which the Cu-II atoms exhibit two different octahedral coordination geometries. The L ligand coordinates to two Cu-II centres in a tridentate manner, with the pyrazine ring acting as a bridge linking the Cu-II coordination units and building an infinite one-dimensional chain. Extensive hydrogen bonding among perchlorate anions, water molecules and L ligands results in three-dimensional networks.
