一维材料是化学家和物理学家们非常感兴趣的对象，因为它们显示出惊人的和高度各向异性的电，磁和光学特性。1迄今为止研究的一维导电配合物大多含有平面分子的无限堆叠和非整数形式氧化数，2但只有少数表现出“金属行为”。最近，我们发现了几种镍三价金属（II）衍生物的二硫代羧酸配体结晶为柱状结构，具有二聚体或单体单元。例如，二硫代乙酰基钯（II）络合物存在于两个固态相中。4第一个包含二聚体分子的一维排列，其中CS2掺入柱之间。第二种由单核和双核单元组成，沿晶胞的a轴沿着交替排列。二硫代乙酰基铂（II）配合物则以二聚体Pt_2（CH_3CS_2）_4的形式沿晶体学c轴沿着排列。5在试图获得具有非整数形式氧化态的含硫配体的进一步类似物，并且可能具有“金属行为”的过程中，我们研究了Pt（II）和Pd（II）的二硫代羧酸衍生物与卤代-
One-dimensional materials are the object of intense interest on the part of chemists and physicists because they show spectacular and highly anisotropic electrical, magnetic, and optical properties. 1 Most of the 1-D electrically conductive complexes studied to date contain infinite stacks of planar molecules and nonintegral formal oxidation number of the constituents, 2 but only a few of them show “metallic behavior”. 3 Chain structure is therefore the first requisite for obtaining such behavior.Recently, we found that several nickel-triad metal (II) de-rivatives of dithiocarboxylato ligands crystallize in a columnar structure, with either dimeric or monomeric units. The dithioacetato palladium (II) complex, for example, exists in two solid-state phases. 4 The first one contains a one-dimensional arrangement of dimeric molecules with CS2 incorporated between the columns. The second one consists of mononuclear and binuclear units, alternating along the a axis of the unit cell. On the other hand, the dithioacetato platinum (II) com-plex crystallizes in dimeric units, Pt2 (CH3CS2) 4, stacking in columns along the crystallographic c axis. 5 In an attempt to obtain further analogues with sulfur-containing ligands having nonintegral formal oxidation state, and possibly with “metallic behavior”, we studied the reaction of dithiocarboxylato derivatives of Pt (II) and Pd (II) with halo-
