The synthesis, crystal structure and biological properties of [Co(edtp)Cl)]·NO3·H2O are described, where edtp is N,N,N′,N′-tetrakis(2-hydroxypropyl) ethylenediamine. The Co2+ ion is coordinated by the N,N′,O,O′,O″-pentadentate edtp ligand and a chloride to generate a distorted CoClN2O3 octahedron. The complex exhibits moderate antithrombolytic activity (38 % screened by hemolytic assay) against clots developed by bovine blood and negligible cytotoxicity (5 %) against bovine erythrocytes. Conversely, very high bacterial biofilm inhibition (90 %) was recorded against both Gram-positive and Gram-negative bacterial species.
