摘要
A novel ion-pair palladium（Ⅱ） compound, （NOzBzPy）2[Pd（dmit）2] （NO2BzPy^＋ = 1-（4-nitrobenzyl）pyridinium, dmit^2- = 2-thioxo-1,3-dithiole-4,5-bis（thiolate））, was synthesized and characterized by single-crystal X-ray structure determination. This compound crystallizes in the monoclinic system, space group P21/n with a = 10.4463（11）, b = 8.5627（9）, e = 20.017（2）A, β = 97.7730（10）°, V = 1774.1（3）A^3, Z = 2, C30H22N4O4S10Pd, Mr = 929.52, Dc = 1.740 g/cm^3,μ = 1.155 mm^-1, S = 1.006, F（000） = 936, R = 0.0354 and wR = 0.0675. The most intriguing general structural feature of the compound is the completely segregated columnar stacks of anions and cations. There exist hydrogen-bonding interactions within the cation column.
