Synthesis and crystal structure of silver(I) carboxylate complexes, Ag(P nBu 3)[C(CH 3) 3COO] and Ag(Phen) 2[CF 3COO]·H 2O

Abstract

Ag(P n Bu 3)[C(CH 3) 3COO] ( I) and Ag(Phen) 2[CF 3COO]·H 2O ( II) were synthesized by the reaction of silver (I) carboxylate with the neutral ligand in absolute ether and ethanol, respectively. Crystal structures of I and II were determined by single crystal X-ray diffraction. The crystal structure of I is built up from dimeric units in which two Ag(P n Bu 3)[C(CH 3) 3COO] molecules are linked by two AgO bonds (2.626 Å). The closest coordination environment of the silver atom consists of two oxygen atoms with average AgO distances of 2.38 Å and one phosphorous atom with a AgP distance of 2.326 Å. The crystal structure of II is formed by infinite rows of [Ag(Phen) 2] + cations between which [CF 3COO] − anions are arranged. Relations between volatility and crystal structures of I and II are discussed.
