This Question Has Multiple Parts Work All The Parts To Get The Most Points The Glycinate Ion H Nch Co2 Formed By D 1 (133.5 KiB) Viewed 49 times
This question has multiple parts. Work all the parts to get the most points. The glycinate ion, H, NCH, CO2, formed by deprotonation of the amino acid glycine, can function as a bidentate ligand, coordinating to a metal through the nitrogen of the amino group and one of the oxygen atoms. Glycinate ion, a bidentate ligand H:0: - 0 : c-c H HỌN Site of bonding to transition metal ion A zinc complex of this ligand has the formula Zn(H2NCH, CO2)2(H2O)2. For this complex, determine the following: a the oxidation state of zinc Oxidation state: +2 Correct The oxidation state of zinc is +2. With a charge of 0 of an overall complex, and 2 neutral H2O molecules and 2 glycinate ions (each with a -1 charge) ligands, zinc has to be +2.
b the coordination number of zinc Coordination number: 6 Correct With 2 bidentate glycinate ligands and 2 monodentate H2O ligands, the coordination number for zinc is 6. Cthe number of unpaired electrons unpaired electron(s) Submit Previous Next
