Metallkomplexe mit α,ω-Bis(2-pyridyl)-alkanen

Abstract

Complexing agents of the type: 2-pyridyl-(CH₂)_n-2-pyridyl with n-values from one to six have been investigated. The stability of the complexes with Co²⁺, Ni²⁺, Cu²⁺, Zn²⁺, Cd²⁺, Ag⁺ and Hg²⁺ have been determined. There is generally a strong decrease in complex stability when n is increased from 0 to 2. An almost constant value is reached by a further increase of the chain length n. The silver and mercury complexes behave exceptionally.
