Tmtacn, tacn, and triammine complexes of (eta 6-arene)OsII: syntheses, characterizations, and photosubstitution reactions (tmtacn = 1,4,7-trimethyl-1,4,7-triazacyclononane; tacn = 1,4,7-triazacyclononane).
A series of (eta 6-arene)OsII complexes containing the saturated nitrogen donor ligands tmtacn, tacn, and NH3 are prepared and characterized. The electrochemical properties and photochemical reactions of these complexes are studied, and the solid-state structures for [(eta 6-p-cymene)Os(tacn)](PF6)2 (1) and [(eta 6-p-cymene)Os(tmtacn)](PF6)2 (2) are determined. Single-crystal X-ray data: 1, orthorhombic, space group Pbca-D2h15 (No. 61), with a = 14.716(3) A, b = 17.844(3) A, c = 18.350(4) A, V = 4819(2) A3, and Z = 8; 2, monoclinic, space group C2-C2(3) (No. 5), with a = 17.322(4) A, b = 10.481(3) A, c = 15.049(4) A, beta = 98.72 degrees, V = 2701(1) A3, and Z = 4.
