[Zn(H₂O)₄]²⁺ : The coordination number is 4, because there are four NH3 ligands. The co-ordination number is again 6 because of the 6 co-ordinate bonds being formed by the central metal ion. In the given complex, C o binds with two a bi-dentate ligand e n ( 2 × 2 = 4 ) and two mono-dentate ligand C l ( 2 × 1 = 2 ). The exceptions are polydentates that have a prefix already in their name (en and EDTA 4-are the most common). In this case, zinc displays a coordination number of 6 and a high affinity for nitrogen [27] and oxygen [28], whereas EDTA is a hexadentate ligand that binds through four oxygen and two nitrogen. Solution For 3. detaco bell menyu EDTA combines with cations to form (a) chelates (b) clathrates (c) non-stoichiometric compounds (d) polymers Answer: (a) chelates One among the following … A monovalent cation which has atomic number 11, makes a compound with a monovalent anion whose atomic number is 17. The diagram shows the structure of the ion with the important atoms and lone pairs picked out. We may be compensated when you click on prod. The most common coordination number is the coordination number 6. iida x aoyama For example, the ligand EDTA, (HO 2 CCH 2) 2 NCH 2 CH 2 N(CH 2 CO 2 H) 2, coordinates to metal ions through six donor atoms and prevents the metals … The number of atom of the ligand that are directly bound to the central metal atom or ion by coordinate bonds is known as the coordinate number of the metal or ion. The federal government gives every U citizen and eligible resident a nine-digit Social Security number. Show transcribed image text. This number of binding sites is called the denticity and ligands are referred to as monodentate (non chelating), bidentate, tridentate, etc. decvs on veterans highway The co-ordination number is again 6 because of the 6 co-ordinate bonds being formed by the central metal ion. ….
