π-Conjugated bridged isomeric diruthenium(II) complexes [(acac)2RuII(μ-DIPQD)RuII(acac)2], 1 (trans) and 2 (cis) (acac- = acetylacetonate, (8E,16E)-N8,N16-diphenylindeno[1,2-b]indeno[2',1'5,6]pyrazino[2,3-g]quinoxaline-8,16-diimine (trans-DIPQD), and (12E,16E)-N12,N16-diphenylindeno[1,2-b]indeno[1',2'5,6]pyrazino[2,3-g]quinoxaline-12,16-diimine (cis-DIPQD) were separated and structurally characterized. The structures of the rac (ΔΔ/ΛΛ) forms of 1 and 2 exhibit two units of Ru(acac)2, linked to adjacent pyrazine
