Lewis-Base Adducts of Group 11 Metal(I) Compounds. XXXIV : 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)?, ߠ96.9(1)ଠZ 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)?, Ag-N 2.385(9), 2.347(11)?, with Ag-Cl-Ag 102.62(9)໠the largest angle in the silver environment is 120.3(2)ਃl-Ag-N).
