SOLUBLE RUTHENIUM(II) COORDINATION POLYMERS BEARING BULKY SIDE-GROUPS

Ruthenium(II) coordination polymers bearing lateral methyl and adamant ylmethylene substituents, respectively, have bean prepared via reactio n of equimolar amounts of tetrapyridophenazine 2 and the novel metal m onomers [Ru(R(2)bpy)Cl-3](x) (3a,b)(R: a, methyl; b, adamantylmethylen e). Moreover, the bulky adamantylmethylene substituents are shown to c ause a significantly more extended chain conformation of the intrinsic ally rigid, ribbon-like coordination polymers 1 than is found for othe r polymers of this kind available so far.
