Transition metal complexes are generally bound by coordinate covalent bonds.
2.
A sixth position can reversibly bind oxygen by a coordinate covalent bond, completing the octahedral group of six ligands.
3.
However, in practice EDTA is usually only partially ionized, and thus forms fewer than six coordinate covalent bonds with metal cations.
4.
In this pH range, the amine groups remain protonated and thus unable to donate electrons to the formation of coordinate covalent bonds.
5.
"' Coordination "'refers to the " coordinate covalent bonds " ( dipolar bonds ) between the ligands and the central atom.
6.
A coordinate covalent bond is formed between the terminal peptide and a C = O group attached to zinc, which gives the carbon a positive charge.
7.
In the former, it has been suggested that the carbon atom attaches via a coordinate covalent bond to an oxygen atom from the substrate through its free bonds.
8.
Disodium EDTA ( often written as "'Na 2 H 2 Y "') only forms four coordinate covalent bonds to metal cations at pH values d " 12.
9.
The ability of EDTA to potentially donate its six lone pairs of electrons for the formation of coordinate covalent bonds to metal cations makes EDTA a "'hexadentate "'ligand.
10.
:: So for the example given, would the hybridization be 3 unshared pairs + 1 pair from the coordinate covalent bond = sp 3 ? talk ) 01 : 04, 17 July 2008 ( UTC)
