Mixed transition-metal complexes based on multitopic 1,3,5-triethynyl- and 1-diphenylphosphino-3,5-diethynyl-benzene linking units

► Fe, Cr, Au, Ti and Cu as constitutional metal atoms for heteromultimetallic complexes. ► Carbon-rich linker groups for the approprpaite metals. ► Electrochemistry for electron transfer studies.
