The reactions between[Mo(NO)(tp*)I₂] {tp* =HB(3,5-Me₂C₃HN₂)₃}and HE-EH {HE-EH =1,3-(HSCH₂)₂C₆H₄and 1,4-(HSCH₂)₂C₆H₄}afford the cyclic dimers[Mo(NO)(tp*)(E-E)]₂ and cyclic trimers[Mo(NO)(tp*)(E-E)]₃.These reactions also produce the monometallomacrocycles[Mo(NO)(tp*)(E-E)_x](x = 2, 3) and, from1,3-(SCH₂)₂C₆H₄,[Mo(NO)(tp*){(3-SCH₂C₆H₄CH₂)₂S}].The reaction between [Mo(NO)(tp*)I₂]and 1,2-(HSCH₂)₂C₆H₄ affords, asits major product, the chelate complex[Mo(NO)(tp*){1,2-(SCH₂)₂C₆H₄}],nometallomacrocycles being found among the reaction products in thiscase. Cyclic voltammograms of themacrocyclic complexes contain single reduction waves in the region-1.374 to -1.486 V (vs ferrocene/ferrocenium), and the binuclear metallomacrocycles show noelectrochemically resolvable metal-metal interactions.The molecular structures of[Mo(NO){HB(3,5-Me₂C₃HN₂)₃}{1,4-(SCH₂)₂C₆H₄}_n](n = 2, 3) have been determinedcrystallographically:[Mo(NO){HB(3,5-Me₂C₃HN₂)₃}{1,4-(SCH₂)₂C₆H₄}₂],C₃₁H₃₈BMoN₇OS₄,orthorhombic,space group Pna2₁, a =16.193(8) Å, b = 12.878(5) Å, c =16.620(5) Å, Z = 4;[Mo(NO){HB(3,5-Me₂C₃HN₂)₃}{1,4-(SCH₂)₂C₆H₄}₃],C₃₉H₄₆BMoN₇OS₆,monoclinic space group P2₁/n,a = 19.140(5) Å, b =10.708(3)Å, c = 22.072(5) Å, ges/gifchars/beta2.gif" BORDER=0 ALIGN="middle"> = 100.73(2)ges/entities/deg.gif">,Z = 4.
