Distorted octa­hedral environments in tri­carbonyl­rhenium(I) complexes of 5-[2-(2,4,6-tri­methyl­phenyl)diazen-1-yl]quinolin-8-olate and 5,7-bis­[2-(2-methyl­phenyl)diazen-1-yl]quinolin-8-olate

The Re^I centres of the tri­carbonyl­rhenium(I) complexes of 5-[2-(2,4,6-tri­methyl­phenyl)diazen-1-yl]quinolin-8-olate and 5,7-bis­[2-(2-methyl­phenyl)diazen-1-yl]quinolin-8-olate are facially surrounded by the ligands in a slightly distorted octa­hedral environment. Both structures exhibit inter­molecular C—H...O inter­actions.
