Synthesis and X‐ray Structural Study on the Complexes of Silver(I) Halide with Tricyclohexylephosphine, Diphenyl‐(2,4,6‐trimethoxy)phenylphosphine, Phenyl‐2,4,6‐trimethoxyphenyl phosphine, and Tris(2,4,6‐trimethoxy)phenylphosphine

A diverse array of structures for the complexes of silver(I) halide with triphenylphosphine (PPh3) has been studied. The complexes may be described as being of the type [AgX(PPh3)n] (X = Cl, Br or I). The value of n varies in the range of 1–3. This also indicates that the stoichiometry of the complexes is in the range of 1–3. The complex with stoichiometry 1:1 is a tetramer. There are two structural types of tetramer reported, termed cubane and step or chair. The cubane structure has been reported for [AgX(PPh3)]4 (X = Cl, Br or I), while the step structure has only been reported for [AgI(PPh3)]4. The complex with stoichiometry 1:2 may be a monomer or a dimer. The monomer has a quasi trigonal planar structural type and has only been reported for [AgBr(PPh3)2]. The dimer has been reported for [(PPh3)2Ag(μ‐X)2Ag(PPh3)2] (X = Cl or Br) with silver atom in the distorted tetrahedral environment. The complex with stoichiometry 1:3 has a distorted tetrahedral structural type and has been reported for [AgX(PPh3)3...
