本文从含溶剂化锌（II）、苯硫酚和卤素离子的醇-丙酮溶液中结晶出配合物（Me 4 N）2 [Zn 4（SPh）8X 2]（X= Cl，Br），（Me 4 N）2 [Zn 4（SPh）9 Cl]和（Me 4 N）2 [Zn 4（SPh）10]，并用这些和其它物质的平衡来描述和解释。[（g-SPh）6（ZnSPh）4] 1 2~的金刚烷笼状结构也存在于[（g-SPh）6（ZnSPh）2（ZnX）2] 2 45 ~（X= Cl，Br（同构））中，具有两个末端卤化物配体。没有证据表明卤素取代超过两个末端位置。金刚烷笼的轻微变形，主要是在bridgingsulfur原子的位置，与不同的苯环方向，而不是氯取代，没有检测到的笼的几何形状的影响。平均距离为Zn-S（Cl）tórminai= 2.257±0.007和Zn-S桥连= 2.358±0.005。晶体数据：a= 12.377（2）A，B= 16.592（3）k，c= 16.967（3）A，a= 76.68（1），ε = 69.92（1）6，y= 72.57（1），PI，Z= 2，4138个反射峰，R= 0.052。
The crystallizationof complexes (Me4N) 2 [Zn4 (SPh) 8X2](X= Cl, Br),(Me4N) 2 [Zn4 (SPh) 9Cl], and (Me4N) 2 [Zn4 (SPh) 10] from alcohol-acetonesolutions containing solvated zinc (II), benzenethiolate, and halide ionsis described and interpreted in terms of equilibriainvolving these and other species. The adamantane cage structure of [(/¿-SPh) 6 (ZnSPh) 4] 1 2~ occurs also in [(g-SPh) 6 (ZnSPh) 2 (ZnX) 2] 2 45"(X= Cl, Br (isostructural)) with two terminal halide ligands. No evidence for halide substitution of more than two terminal positions has been obtained. Slight distortions of the adamantane cage, principally in the positions of the bridgingsulfur atoms, are associated with differentiated phenyl ring orientations, not the chloride substitution which has no detectable influence on the geometry of the cage. Mean distances are Zn-S (Cl) tórminai= 2.257±0.007 and Zn-Sbridging= 2.358±0.005 A. Crystal data: a= 12.377 (2) A, b= 16.592 (3) k, c= 16.967 (3) A, a= 76.68 (1), ß= 69.92 (l) 6, y= 72.57 (1), PI, Z= 2, 4138 observedreflections, R= 0.052.
