✦ Synopsis
Germanium(I) / Tetrahalgenodigermanate(2-) / Octahedral [Ge 6 ] 2-clusters / Organometallic derivatives / Carbonyl complexes / Chromium / Tungsten GeI 2 reacts with [M 2 (CO) 10 ] 2-(M = Cr, W) leading to reductive coupling of two GeI 2 units to produce the [Ge 2 I 4 ] 2-ligands of [{(OC) 5 M}I 2 Ge-GeI 2 {M(CO) 5 }] 2-(1a and 2a). The [Ph 4 P] salts of these anions have been characterised by Xray structure analyses as have the [Ph 4 P] salts of [{(OC) 5 M}Cl 2 Ge-GeCl 2 {M(CO) 5 }] 2-(1b and 2b) obtained from the iodo derivatives 1a and 2a by halide metathesis with [Ph 4 P]Cl.
