square-antiprism geometries. The SePh compound is the only seven coordinate (4Se, 3N) product, and the fluorinated thiolate is distinctive in that the structure contains two dative interactions between Th and fluoride, to give a nine coordinate (3N, 4S, 2F) structure. The EPh compounds decompose thermally to give ThE2 and EPh2, while the fluorinated compounds give primarily ThF4, E2(C6F5)2, and E(C6F5)2.
cha硫属元素化物Th(ER)4(E = S,Se; R = Ph,C 6 F 5)形成具有多种配位数的吡啶配合物。(py)4 Th(SPh)4,(py)3 Th(SePh)4,(py)3 Th(SC 6 F 5)4和(py)4 Th(SeC 6 F 5)4四种化合物,已通过光谱方法和低温单晶X射线衍射进行了分离和表征。其中两个产品(py)4 Th(SPh)4和(py)4 Th(SeC6 F 5)4,具有经典的八个坐标A 4 B 4的方形反棱镜几何形状。SePh化合物是唯一的七个坐标(4Se,3N)产物,氟化硫醇盐的独特之处在于该结构在Th和氟化物之间包含两个相对的相互作用,从而形成一个九坐标(3N,4S,2F)结构。EPh化合物热分解产生ThE 2和EPh 2,而氟化化合物主要产生ThF 4,E 2(C 6 F 5)2和E(C 6 F 5)2。
