Osmium complexes phthalocyanine

Ruthenium and Osmium Phthalocyaninates - By cyclization of phthalodinitrile with RuC13(H20)3 or Os04 in the presence of carbon monoxide or with the corresponding trimetal dodecacarbonyls, the pure complexes RuCO(Pc) Py and OsCO(Pc) Py have been obtained in good yields [108]. o-Cyanobenzamide and RuC13(H20)3 [109] produced so-called crude Ru(Pc) and, after extraction with pyridines, complexes like Ru(Pc)Py2. 

Osmyl complexes of phthalocyanine have been claimed. Reaction of 0s04 and 1,2-dicyanobenzene at 180°C gives the dark blue Os02-Pc C6H4(CN)2, which is paramagnetic (/u,eff = 1.4 BM at 20°C) so this could well be an osmium(IV) or even an osmium(III) species (231). Another osmyl species claimed is 0s02Pc-3PhNH2, made from... 

Reaction of (NH4)20sCl6 with EPhj (E = P or As) allows isolation of trans-OsCl4(EPh3)2. A paramagnetic, octahedral osmium(iv) complex of 3,3 -diamino-4,4 -dihydroxydiphenyl-sulphone has been prepared.The thermal decomposition of Os(phthalocyanine)S04 has been studied.

Osmium tetroxide was heated with phthalonitrile to form an osmium derivative which was crystallized from concentrated sulfuric acid as the diamagnetic sulfato-osmium(IV) phthalocyanine 25). A six-coordinate sulfato-bridged structure was proposed, but no infrared data were cited in support of this idea. The complex is extremely soluble in concentrated sulfuric acid. The diamagnetism is unexpected. Osmium(IY) has a d4 configuration, and a moment above 2.0 B.M. might have been predicted. The...
