    Description / Table of Contents: Isocyanide Complexes, IV. Synthesis and Reactions of Hg(CN)2-Bridged Metal CarbonylsFrom K[Cr(CO)5CN] (1) and MCl2 (M=Hg, Cd, Zn) the metal-bridged complexes {(CO)5CrCN}2M (2, 9, 10) are synthesized. In an analogous reaction with MeHgCl or PhHgCl, resp., the compounds (CO)5CrCNHgR (R=Me 6, Ph 7) are obtained. Like 2 these complexes show a distinct CN/NC-coordination isomerism. In a THF solution of 2 (M=Hg), mer-[(THF)3Cr{(CO)5CrCN}3] (3) is formed on heating. The corresponding fac-isomer 4 is obtained from CrCl3(THF)3 and 1. [NEt4]CN reacts with 2 to yield [NEt4]2-[Hg{Cr(CO)5CN}4] (5). From (CPh3)2 and 2 the isocyanide complex (CO)5CrCNCPh3 (8) is formed. IR und NMR spectra of the complexes are discussed.
    Notes: Aus K[Cr(CO)5CN] (1) und MCl2 (M=Hg, Cd, Zn) werden die Metall-verbrückten Komplexe {Cr(CO)5CN}2M (2, 9, 10) dargestellt. Analog erhält man mit MeHgCl bzw. PhHgCl die Verbindungen (CO)5CrCNHgR (R=Me 6, Ph 7), die ebenso wie 2 eine CN/NC-Koordinationsisomerie aufweisen. THF-Lösungen von 2 (M=Hg) bilden beim Erhitzen mer-[(THF)3Cr{(CO)5CrCN}3] (3). Das entsprechende fac-Isomere 4 ist aus CrCl3(THF)3 und 1 erhältlich. Mit [NEt4]CN bildet 2 [NEt4]2[Hg{(CO)5CrCN}4] (5). (CPh3)2 und 2 setzen sich zum Isocyanidkomplex (CO)5CrCNCPh3 (8) um. IR- und NMR-Spektren der Verbindungen werden diskutiert.
