Abstract

1 min read

An iridium-sulfur-nitrogen heterobicycle having a [4.3.0] framework is present in the air- and moisture-sensitive title compound 1. This surprising result was obtained by structure analysis of the long-known compound. The tridentate coordination of S4N4 to a transition-metal haldie is new; usually, the coordination occurs through a lone pair of electrons on a nitrogen atom. The bulky triphenylphosphane group is omitted in the picture on the right.
