Abstract：

A　supramolecular　assembly　[Fe-2(CO)(6)(1,8-S-2-2-CH2OCO-4-PyC10H5)]center　dot　ZnTPP　(2)　of　a　pyridyl-functionalized　diiron　naphthalene-1,8-dithiolate　complex　[Fe-2(CO)(6)(1,8-S-2-2-CH2OCO-4-PyC10H5)]　(1)　and　zinc　tetraphenylporphyrin　(ZnTPP)　was　synthesized　and　thoroughly　characterized.　X-ray　structural　studies　showed　the　noncovalent　coordination　of　the　pyridyl　nitrogen　of　1　to　the　zinc　in　ZnTPP　had　a　minor　effect　on　the　geometry　of　the　diiron　cluster,　only　leading　to　Fe-Fe　distance　of　2　slightly　shorter　than　in　1.　Electrochemical　studies　verified　that　the　complex　1　possessed　an　electrocatalytic　proton　reduction　activity　in　acetonitrile,　when　using　p-toluenesulfonic　acid　as　a　proton　source.　The　steady-state　fluorescence　studies　of　assembly　2　revealed　that　the　excited　state　of　associated　ZnTPP　could　be　significantly　quenched　by　the　diiron　core.　(C)　2016　Elsevier　B.V.　All　rights　reserved.
