Reactions of MeSPCl2, EtSPCl2 and Cl[graphic omitted], respectively with Co2(CO)8 in the presence of zinc powder give the Co6 clusters [Co6(µ6-P)(µ-SMe)3(CO)12]1, [Co6(µ6-P)(µ-SEt)3(CO)12]2 and [Co6(µ6-P)(µ4-SCH2CH2S)(µ-µ-[graphic omitted])(CO)12]3 respectively; in 1 six Co atoms form a boat-shaped array consisting of a basal square of four cobalt atoms with two opposite edges bridged by two apical Co atoms, with the metal arrangement surrounding a semi-interstitial P atom, and with two µ-SMe ligands bridging underneath the basal square and another bridging µ-SMe side-linked to the basal square.
MeSPCl2、EtSPCl2和Cl分别与Co2(CO)8在锌粉存在下反应,得到Co6簇[Co6(µ6-P)(µ-SMe)3(CO)12]1、[Co6(µ6-P)(µ-SEt)3(CO)12]2和[Co6(µ6-P)(µ4-SCH2CH2S)(µ-µ-[省略图形])(CO)12]3;在第一种结构中,六个钴原子形成一个船形阵列,由四个钴原子构成的基底正方形,两条相对边由两个顶端钴原子桥接,金属排列环绕着一个半间隙的磷原子,并且有两个µ-SMe配体在基底正方形下方桥接,另一个µ-SMe配体侧向连接到基底正方形。
