Synthesis and Crystal Structure of Thallium(III) Bicyclic Phthalocyanine.

Synthesis, Spectral Characterisation and Crystal Structure of (1,24-Bicyclophthalocyaninato)bismuth(III)

“…They suggested that the blueϪviolet colour was characteristic of all phthalocyanines in which there is full delocalisation of π-electrons along the inner 16-membered ring, and that green was the characteristic colour of bicyclophthalocyanines in which the π-electron delocalisation is interrupted. [7,8] Effectively, all reported bicyclophthalocyanines complexes with the (1,17-Pcc) ligand are green. As proved by X-ray analysis, 1 and 2 are also bicyclophthalocyanines in which the π-electron delocalisation is interrupted: 2 is yellowϪgreen, 1 is not green, but bright orange, closer to red than to yellow.…”

The dihedral angle between mean plane VI and P3 is 7.9°, with an estimated standard deviation of 4.7°so that the co-crystallised molecule may be considered as nearly parallel to the benzopyrrole VI.…”

“…This new complex was fully characterised by UV/Vis and IR spectroscopy, also reported here. gadolinium(III), thallium(III), and cerium(III), [6] and reported the molecular structure of the Gd, [7] In, [6] and Tl [8] complexes. All these complexes contain a ligand with the same overall formula (C 48 H 24 N 13 ), but these ligands have different structures and point symmetries.…”

Synthesis and characterisation of bismuth(III) phthalocyaninate complex: [BiPc]4[Bi6I11Cl11]

“…The composition and structure of the metals of the group 15-phthalocyanines, in which the metal has +3 oxidation state, can be expressed by the general formula of MPcX (X = monovalent anion) [8,9], M 2 Pc 3 [10,11], MPc 2 X or MPc 2 with one monooxidised phthalocyaninate radical ring (Pc ÀÅ ) [12,13]. Besides the mono-doubledecker and triple-decker phthalocyaninato complexes, the bismuth(III) similar to other metals(III) can form bicyclic phthalocyanines, in which the delocalisation of the p-electron in the inner 18p-electron ring is interrupted by two head carbon atoms with the sp 3 hybridisation [14][15][16][17].…”

Re(CO)3-Templated Synthesis of α-Amidinoazadi(benzopyrro)methenes

“…Similar conversions have been seen in the “helmet” and bicyclic phthalocyanines. 13–21 The structures of compounds 1–3 , 5 , and 9 are shown in Figure 2. In all cases, the rhenium(I) ion adopts an octahedral geometry and is coordinated by a neutral tridentate A 3 DBM ligand and the remaining positions are occupied by the expected three facially coordinated carbonyl ligands.…”
