(Porphyrinato)bis(phthalocyaninato)dilanthanide(III) complexes presenting a sandwich triple-decker-like structure

Synthesis, Crystal Structure and Spectral Characterization, of a New Phase of Tris(phthalocyaninato)dibismuth(III), Bi2(Pc)3

“…Similar to the comparisons made for lanthanoid phthalocyanines in the literature, [15,34,35] structure with those of double-decker compounds Bi(Pc) 2 ,CH 2 Cl 2, [12] and Bi(Pc) 2 I 1.5 , [11] and with that of the bismuth monophthalocyanine-bismuth iodide complex. [10] The later contains a BiPc ϩ moiety, and has the shortest distances for BiϪCt (1.14 Å ) and BiϪN iso (2.27 Å ).…”

Synthesis and Characterization of Mixed Phthalocyaninato and meso‐Tetrakis(4‐chlorophenyl)porphyrinato Triple‐Decker Complexes − Revealing the Origin of Their Electronic Absorptions

“…Both compounds are isostructural and crystallize in the same tetragonal system with a P 4/ n space group together with a disordered CH 2 Cl 2 molecule. It is worth noting that structurally characterized mixed‐ring triple‐deckers remain rare so far, and to the best of our knowledge they are limited to [(TPP)Ce(Pc)Gd(OEP)] (TPP = meso ‐tetraphenylporphyrinate; OEP = octaethylporphyrinate),7 [Ce 2 (Pc) 2 (TOMePP)] [TOMePP = meso ‐tetrakis(4‐methoxyphenyl)porphyrinate],8 [Ce 2 {Pc(OMe) 8 }(TPP) 2 ] [Pc(OMe) 8 = 2,3,9,10,16,17,23,24‐octamethoxyphthalocyaninate],8 [Nd 2 (Pc) 2 (TOMePP)],9 and [Nd 2 (Nc)(OEP) 2 ] (Nc = naphthalocyaninate) 4d…”

Multistate molecular information storage using S-acetylthio-derivatized dyads of triple-decker sandwich coordination compounds

“…Halfsandwich formation is generally complete in about 5 h and is readily observed by a characteristic change in the absorption spectrum [39,40]. Thus, reaction of porphyrin 3 and Eu(acac) 3 ·nH 2 O in refluxing 1,2,4-TCB afforded the half-sandwich complex, to which was added Eu(t-Bu 4 Pc) 2 , affording the iodophenylsubstituted triple decker 7 in 82% yield (Scheme 4).…”
