# Amidinate- and Dithiolene-Based Silicon Complexes

## TL;DR

This paper reports the synthesis and characterization of new silicon complexes containing amidinato and dithiolene ligands, including the first structurally confirmed silicon(II) dithiolene complex.

## Contribution

The first structurally characterized silicon(II) dithiolene complex is synthesized and analyzed.

## Key findings

- Silicon complexes 5–7 were synthesized using amidinato-silylene chloride and dithiolene derivatives.
- Complex 7 is the first structurally characterized silicon(II) dithiolene complex.
- Structural and bonding features were studied using experimental and theoretical methods.

## Abstract

Reactions of the amidinato-silylene chloride PhC(tBuN)2SiCl (1) with
imidazole-based
dithione dimer 2, lithium dithiolene radical 3, and dithiolate dimer 4 result in the synthesis of
a series of silicon complexes 5–7, respectively, containing both amidinato and dithiolene ligands. 7 is the first structurally characterized silicon(II) dithiolene
complex. The structural and bonding characteristics of 5–7 have been probed by both experimental and
theoretical methods.
