Abstract

Abstract : The reactions of cyclic selenoureas with silver(i ) salts yield new coordination complexes with sterically-controlled solid state aggregation. Abstract : The coordination chemistry of two selenourea ligands (SeIMes and SeIPr) towards silver(i ) triflate and silver(i ) nitrate was investigated. Two aggregation modes were observed in the solid state, strongly influenced by the size of the aromatic substituents on the ligand. With mesityl groups, selenium-bridged bimetallic motifs [AgX(SeIMes)]2 were obtained, while for the bulkier diisopropylphenyl groups ion-separated species of formulae [Ag(SeIPr)2 ] + [X] − were obtained. Recrystallization of [Ag(NO3 )(SeIMes)]2 from hot methanol resulted in the formation of a unique coordination polymer featuring three silver environments. Characterization of the complexes by NMR spectroscopy and mass spectrometry suggested all complexes adopt the ionic aggregation mode in methanol solution.
