Main Group Metal Directed Self-Assembly in a Tetrameric Trimethyltin(IV)N-nitroso-N-phenylhydroxylaminato Complex Containing an Unprecedented 20-Membered Inorganic (Carbon-Free) Metallamacrocycle

Abstract: Tetrakis[trimethyl(N‐nitroso‐N‐phenylhydroxylaminato)tin(IV)] was synthesized by reaction of cupferron ([PhN(O)NO]NH4) with trimethyltin(IV) chloride. The complex was characterized by X‐ray diffraction analysis, FT‐IR and FT‐Raman spectroscopy. An X‐ray structural analysis of the title complex [Me3Sn(O2N2Ph)]4 reveals the first example of a bridging coordinated cupferronato ligand. This coordination pattern leads to an unprecedented inorganic 20‐membered (carbon‐free) metallamacrocycle Sn4O8N8 in which four Me… Show more

Exaggerated anticipatory anxiety is common in social anxiety disorder (SAD). Neuroimaging studies have revealed altered neural activity in response to social stimuli in SAD, but fewer studies have examined neural activity during anticipation of feared social stimuli in SAD. The current study examined the time course and magnitude of activity in threat processing brain regions during speech anticipation in socially anxious individuals and healthy controls (HC). Method Participants (SAD n = 58; HC n = 16) underwent functional magnetic resonance imaging (fMRI) during which they completed a 90s control anticipation task and 90s speech anticipation task.
