  Synthesis, spectroscopy, crystal structure and magnetism of tetrakis(2-aminopyrimidine)bis(μ-methoxo)bis(perchlorato)dicopper(II): a rare case of distortion isomerism

  摘要：

  The dinuclear compound [Cu(ampym)(2)(mu-CH3O)(ClO4)](2) (ampym = 2-aminopyrimidine) has been synthesized and characterized by X-ray crystallography and infrared spectroscopy. In addition, EPR and magnetic measurements have been performed and related to the dinuclear structural details.The compound crystallizes in the monoclinic space group P2(1)/c, with a = 8.0190(13), b = 18.2500(11), c = 10.955(2) Angstrom, beta = 116.390(13)degrees, V = 1436.2(4) Angstrom(3) and Z = 2. The coordination geometry around the Cu(II) ion is distorted square pyrimidal with the basal plane formed by two nitrogen atoms of two ampym molecules (Cu-N distances 2.002(3) and 2.031(3) A) and two oxygen atoms of the bridging methoxo molecules (Cu-O distances of 1.936(2) and 1.937(3) A). The apical position is occupied by a semi-coordinated oxygen of a perchlorate anion (Cu-O distance 2.442(2) Angstrom). The H-bonds, formed by the amino group and the uncoordinated pyrimidine nitrogen atom of a neighbouring ampym molecule, give rise to an interesting Watson-Crick type pairwise aggregation of ampym ligands.In the far-IR, the Cu-N vibrations are observed at 443 and 265 cm(-1), and the Cu-O are observed at 353 and 240 cm(-1). At room temperature the compound gives an EPR silent behaviour and magnetic susceptibility measurements, down to 4 K, agree with a strong antiferromagnetic interaction having a very large singlet-triplet splitting (J = -621 cm(-1)). The title compound appears to be a distortion isomer of a recently reported X-ray structure of identical stoichiometry. (C) 2004 Elsevier Ltd. All rights reserved.
