Abstract A series of linear and tripodal tetradentateligands containing an amine-bis(phenolate) core were synthesized by Mannich condensations. Treatment of these ligands with MoO2(acac)2 (acac = acetylacetonate) in dichloromethane and methanol at room temperature gave the corresponding cis-dioxomolybdenum(VI) complexes in good yields. All these complexes were characterized by a wide range of spectroscopic
