Rottgers and Sheldrick have recently reported that l,10-dithia-18-crown-6 1 formed lamellar coordination polymer with Cul and ion-ligating iodocuprate(i) based on two-dimensional coordination networks with Cul and alkali metal cations <2000MI271>. Both anionic frameworks contain characteristic iodocuprate(l) chains that are bridged in a /r-Sl,S10 manner by 1. However, the structure-directing influence of the alkali metal cation manifests itself in both the connectivity pattern and the stoichiometry of the resulting Cul-based network. [Pg.830]

Transport of Silver Perchlorate by Lipophilic Monothia- and Dithiacrown Ethers. For lipophilic monothia-15-crown-5 16, dithia-15-crown-5 12 and dithia-18-crown-6 13, transport of Na, Cd ", Hg, Pb and Zn as the perchlorates was undetectable. However, all three macrocycles exhibited efficient transport of silver perchlorate. The Ag transport rates for 16,12 and 13 were 7.92 0.05, 7.52 0.15 and 6.87 0.05 X lO" mole/24 hours, respectivley. Thus the soft Ag cation was transported with almost equal efficiency by mono- and dithiacrown ethers which suggests that only one soft sulfur donor atom interacts with the soft Ag. ... [Pg.161]
