Comprehensive Coordination Chemistry II. Coordination by J. A. McCleverty, T.J. Meyer

By J. A. McCleverty, T.J. Meyer

Accomplished Coordination Chemistry II (CCC II) is the sequel to what has develop into a vintage within the box, accomplished Coordination Chemistry, released in 1987. CCC II builds at the first and surveys new advancements authoritatively in over 2 hundred newly comissioned chapters, with an emphasis on present developments in biology, fabrics technology and different components of latest medical curiosity.

405 Bridging SCN ligands will naturally have both N– and S–bound ends. Such ligands are found in the 1:1 TMEDA complex of lithium thiocyanate, (LiSCNTMEDA)n prepared from solid NH4SCN and BunLi in TMEDA/hexane. 395 The detection of radicals with EPR spectroscopy suggests that the reaction proceeds via an electron-transfer mechanism. Heterobimetallic species containing -SCN ligands are found in the polymeric chain structures [K(18-crown-6)(5-C5Me5)2Yb(NCS)2]1,409 [K(18-crown-6)(-SCN)]2UO2(NCS)2(H2O),410 and Figure 35 The structure of complex formed between (E)-9,10-diphenyl-2,5,8,11,14,17-hexaoxaoctadec-9-ene and NaSCN.

Some of these complexes can adopt a variety of coordination modes; in Rb(18-crown-6)(N(PPh2)2), the phosphinoamide is P,Pligated,492 whereas in (THF)3LiN(PPh2)2, the ligand is bound 2-P,N. 498 The utility of some of these complexes as ligand transfer reagents has been investigated. Thus from the reactions of ZrCl4 with {(TMEDA)Li[CH(PMe2)(SiMe3)]}2, a mixture of the compounds Cl(4 À n)Zr[CH(PMe2)(SiMe3)]n (n ¼ 1–4) has been characterized with NMR spectroscopy. 499,500 Figure 52 The structure of solvent-free [LiP(SiMe3)2]6.

The alkyl groups have been removed for clarity. carboxylates, diketonates, enolates, and alkoxides and aryloxides are considered here, are found in a vast array of s-block complexes. , precursors to metal oxides), and the biological realm (water and oxygencontaining organic functional groups play a critical role in defining the structure and reactions of many proteins and enzymes). (i) Carboxylates Compared to other s-block metal complexes with anionic oxygen donors, the metal carboxylates are particularly robust; although often hygroscopic, they will not decompose upon absorption of water, and are as a class quite thermally stable.
