Halogenoargentate ions three-coordinated metal centers

Mononuclear anions, halogenocuprate 1) and halogenoargentate(I) ions four-coordinated metal centers, 37 19 three-coordinated metal centers, 37 7-11 Mononuclear iron-sulfur clusters, 47 219 EPR spectra, 47 423-425 EPR spectra, 47 448... 

Discrete trinuclear halogenocuprate(I) or halogenoargentate(I) species containing solely three-coordinated metal centers have not been reported hitherto. An [Ag3I6]3 ion in which one of the silver(I) atoms is three coordinated, whereas the remaining two exhibit tetrahedral coordination geometry has, however, recently been isolated (81) (cf Section II,C,3).
