Inter and intramolecular hydrogen bonding; bThe breakage of hydrogen bonding and the deprotonation of both the hydroxyl groups (phenolic), that is, hydrazide –OH and pyrone –OH and their M–O coordination; cNo shift of lactone vC=O at 1710 (s) cm−1; and vC–O–C at 1010 (s) cm−1 suggests noninvolvement in complex formation; shift of hydrazide, phenolic vC–O and vC=N indicate participation in complexation. |
