Abstract
Abstract The new facially coordinating tripod ligand 3,3-bis(1-methylimidazol-2-yl)propionate (bmip) has been studied. A synthetic route to sodium 3,3-bis(1-methylimidazol-2-yl)propionate (Na[bmip], 2a ) and its hydrochloride (Hbmip · 2HCl, 2b ) is reported. The electronic properties of Hbmip were calculated by DFT methods and are compared to those of structurally similar bis(pyrazol-1-yl)acetic acids. The ligand was applied in the synthesis of the two tricarbonyl complexes [Re(bmip)(CO) 3 ] ( 3 ) and [Mn(bmip)(CO) 3 ] ( 4 ). Methyl 3,3-bis(1-methylimidazol-2-yl)propionate (bmipme) ( 1 ), which is the precursor of Hbmip, and the complexes [Re(bmip)(CO) 3 ] ( 3 ) and [Mn(bmip)(CO) 3 ] ( 4 ) were characterised by single crystal X-ray analysis.
