“…Later we developed a more convenient method for the preparation of pure PcRu via the corresponding bisisoquinoline complex PcRu(iqnl) 2 [2] which is readily available and can be thermally decomposed at 250°C with formation of pure PcRu [3]. Pure (tbu) 4 PcRu [4], (tbu) 4 NcRu [4] and NcRu [5] (Nc = 2,3-naphthalocyaninato) were also prepared by us using a similar method.…”

Tetrakis(trimethysilyl)phthalocyaninatoruthenium(II) (5) has been synthesized via the biaxially coordinated (( CH 3)3 Si )4 PcRu (3- Clpy )2 (2) complex by thermal decomposition of the axial ligands of 2. (( CH 3)3 Si )4 PcRu (5) was characterized by NMR, IR and UV-vis spectroscopy and elemental analysis. The trisubstituted (( CH 3)3 Si )3 PcRu (3- Clpy )2 (3) and disubstituted (( CH 3)3 Si )2 PcRu (3- Clpy )2 (4) complexes, formed as side products during the thermolysis of 2, could be isolated and characterized.

Bridged 2,3‐naphthalocyaninatoruthenium oligomers {[MacRu(L)]n} were synthesized and characterized using solid‐state methods. For comparison, soluble t‐butyl substituted phthalocyaninatoruthenium oligomers were prepared and their chain length examined by 1H NMR spectroscopy. The powder conductivities of all bridged compounds ([MacRu(L)]n) were measured and the dependence of the conductivities on the bridging ligands is discussed.
“…The transition metals are Fe, Ru, Os, and Co; and other metals in the oxidation state +II were taken as central metals. The ligands (L) are linear π‐electron‐containing organic molecules bonded to the metal atom 15–26.…”
ABSTRACT:The electronic structures of complexes and one-dimensional metallomacrocycles with cyanide as bridged ligand, such as [MacM(CN) 2 ] − and [MacM(CN)] n [Mac = phthalocyanine, tetrabenzoporphyrine; M = Co(III), Rh(III)] have been investigated using density functional theory. The results of this study show that the intrinsic semiconductivity properties depend on the frontier bands. The valence band is composed by the π-macrocycle orbital. The conduction band for the cobalt polymers is a mixture of orbitals between this metal and the cyanide ligand along of the stacking direction. However, in the rhodium polymers such a band is exclusively composed of the π * system of the macrocycles.
