Abstract

Abstract: The siderophore enterobactin (H, ent) has been crystallized as the vanadium (1V) complex in the compound Kz [V (ent)]. 3DMF from dimethylformamide (DMF) solution. The pseudooctahedral coordination of the metal ion is through the three catechol groups and has approximate C3 molecular point symmetry. The geometry is intermediate between trigonal prismatic and octahedral, with a twist angle of 28O. For comparison, the ...
