ABSTRACT
A novel dicyanoosmium(III) complex, trans-Ph(4)P[Os(III)(salen)(CN)(2)].CH(2)Cl(2).H(2)O (1; Ph(4)P(+) = tetraphenylphosphonium cation, salen(2-) = N,N'-ethylenebis(salicylideneaminato) dianion), has been synthesized and structurally characterized. Reactions of 1 with [Cu(Me(3)tacn)(H(2)O)(2)](ClO(4))(2) (Me(3)tacn = 1,4,7-trimethyl-1,4,7-triazacyclononane) under different conditions produce the 1-D ferromagnetic zigzag chains [Os(salen)(CN)(2)](2)[Cu(Me(3)tacn)].CH(3)OH (2) and [Os(salen)(CN)(2)][Cu(Me(3)tacn)].ClO(4) (3).
