Lewis-Base Adducts of Group 11 Metal(I) Compounds. XXIV. 1:2 Silver(I) Halide/Monodentate Amine Complexes: A Novel Structural Type in 1-2 Silver(I) Chloride Piperidine

Abstract

Recrystallization of silver(I) chloride from neat piperidine (L) yields a 1 : 2 adduct, characterized by a single-crystal X-ray study. Crystals are monoclinic, C2/c, a 20.76(4), b 6.422(7), c 20.69(2)Ǻ, β 96.9(1)°, Z 8; R 0.042 for 1061 'observed' reflections. The structure, the first determined for a 1 : 2 silver(I) chloride/monodentate amine adduct, is an infinite one-dimensional chloro-bridged polymer -AgL₂-Cl-AgL₂-Cl-. About the four-coordinate silver atom, Ag-Cl are 2.524(3), 2.667(3)Ǻ, Ag-N 2.385(9), 2.347(11)Ǻ, with Ag-Cl-Ag 102.62(9)°; the largest angle in the silver environment is 120.3(2)°(Cl-Ag-N).
