| 中文摘要 | a new hydrogen-bonded dinuclear copper(ii) coordination compound has been synthesized from the schiff-base ligand 6-(pyridine-2-ylhydrazonomethyl)phenol (hphp). the molecular structure of [cu-2(php)(2)(h2o2)(2)(clo4)](clo4)- (h2o) (1), determined by single-crystal x-ray diffraction, reveals the presence of two copper(ii) centers held together by means of two strong hydrogen bonds, with o center dot o contacts of only 2.60-2.68 angstrom. temperature-dependent magnetic susceptibility measurements down to 3 k show that the two metal ions are antiferromagnetically coupled (j = -19.8(2) cm(-1)). this exchange is most likely through two hydrogen-bonding pathways, where a coordinated water on the first cu, donates a h bond to the o atoms of the coordinated php at the other cu. this strong o center dot h (water) bonding interaction has been clearly evidenced by theoretical calculations. in the relatively few related cases from the literature, this exchange path, mediated by a (neutral) coordinated water molecule, was not recognized. |
