Abstract: The (+)-enantiomer of 2-[2-(biphenyl-2-yl)-1-methylethyl]-4,5-dihydro-1H-imidazole is known to produce interesting hypotensive effects via inhibition of I1-imidazoline receptors. The crystal structure of its hydrogen oxalate salt, C18H21N2+·C2HO4-, has now been determined at 170 K, allowing the assignment of the absolute configuration of the parent molecule. The solid-state structure is stabilized by a network of hydrogen bonds between the ions.
