What is the Coordination Number of [Fe(EDTA)(H2O)]-?

Im uming that the EDTA is 4- and the overall charge is 1- so the charge on Fe should be 3+. I initially thought that EDTA Tetra-dentate and H2O was Mono-dentate so i figured the Coordination number of Fe was 5 and that was wrong. Can someone please explain this to me. Thanks in advance.
