Is DMG (dimethyl glyoxalate) a bidentate ligand? If yes, then why?because according 2 me, there are 4 site for donation 2 nitrogen lone pairs and 2 oxygen negative.

Question

ruchi yadav · Answer

Yes it is bidentate ligand. Thank You Ruchi Askiitians Faculty

JATIN VERMA · Answer

lone pair of Two nitrogen atoms are not available for donation due to resonance stabilisation. on the other hand two oxygen can easily donate elections without any resonance stabilisation.

NISHANT CHOUDHARY · Answer

Electronegativity of O is high then NSo O doesn`t give lp and O is also connected with H with h-bonding

ankit singh · Answer

nitrogen loan pairs are in stablized resonance so cant use for donation only free lone pairs of oxygen are used for donation

Ipsita Choudhury · Answer

In DMG it is actually the N atoms that act as donors and not the O atoms. This is because, the negative charge over the O atom is involved in pi cloud delocalisation and hence not available for donation. The pi cloud delocalisation will increase the donor ability of O and increase that of N.

Ipsita Choudhury · Answer

Sorry, there was a typo. Donor ability of O is decreased. Also, in cases, where the central metal atom is larger than C, the formation of a 5 membered ring is favoured over that of a 6 membered ring to reduce ring strain. The anionic O is also involved in H bonding with the oxinato proton of another DMG unit in case of the tetracoordinated Ni-DMG complex.
