Heteronuclear chains of four metal atoms including one quadruply bonded dimetal unit, dichromium and dimolybdenum compounds with appended copper(I) atoms

In the formation of molecules complexed with three or more metal atoms, two methods are employed following all-in-one fell swoop or step-by-step strategy. Data point out that in the formation of dichromium and dimolybdenum compounds associated with copper(I) atoms, step-by-step strategy is useful.
