Synthesis and crystal structure of silver(I) carboxylate complexes, Ag(PnBu3)[C(CH3)3COO] and Ag(Phen)[CF3COO]•H2O

Ag((PBu3)-Bu-n)[C(CH3)(3)COO] (I) and Ag(Phen)(2)[CF3COO]-H2O (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((PBU3)-B-n)[C(CH3)(3)COO] molecules are linked by two Ag-O bonds (2.626 Angstrom). The closest coordination environment of the silver atom consists of two oxygen atoms with average Ag-O distances of 2.38 Angstrom and one phosphorous atom with a Ag-P distance of 2.326 Angstrom. The crystal structure of II is formed by infinite rows of [Ag(Phen)(2)](+) cations between which [CF3COO](-) anions are arranged. Relations between volatility and crystal structures of I and II are discussed. (C) 2003 Elsevier Science Ltd. All rights reserved.
