title: Isomorphism in monomeric 1:3 complexes of silver(I) salts with tri-p-tolylphosphine.
abstract: Reaction of silver(I) salts with three equivalents of tri-p-tolylphosphine in CH(3)CN resulted in a series of isomorphous complexes [AgX{P(4-MeC(6)H(4))(3)}(3)] (X = Br, SCN, ClO(4)). These complexes all crystallize in the orthorhombic space group Pna2(1). The complexes with X = Br, SCN are distorted tetrahedral around the silver(I) atom, whereas the ClO(4)(-) complex is distorted trigonal planar around the silver. The new complexes are compared with each other using r.m.s. overlay calculations as well as half-normal probability plot analysis and with the previously reported isomorphous chloride, bromide as well as the non-isomorphous iodide complexes.
