Abstract

Abstract. M r=390.2, monoclinic, P21/a, a= 11.878(1), b=15.698(3), c= 9.027 (1) A, /~= 100.9 (5) ° , U=1653(3)A 3, Z=4, Dx=1.57(1), D,,, = 1.55 (1) g cm -3, 2(Cu Ka) = 1.5418 A,, g = 56.7 cm -l, F(000) = 804, T= 293 K. Final R = 0.047 for 2450 reflections. The V atom is octahedrally coordinated to the vanadyl O, two carboxyl O atoms and one N from the tridentate iminodiacetate ligand, and to two N atoms from the bidentate bipyridyl ligand. The structure consists of individual complexes and two loosely bound molecules of water of crystallization.

Synthesis, molecular structure and properties of oxo-vanadium(iv) complexes containing the oxydiacetate ligand

“…The overall disposition of the ligands in 4 is similar to that found in complex [V(O)(ida)-(bipy)] (ida = iminodiacetate). 28 Also, an interesting comparison can be made with the complex [V(O)(dipic)(phen)] 29 where the ligand dipic (pyridine-2,6-dicarboxylate) can be considered the analogue of oda. In the latter, one phenanthroline N donor lies trans to the V᎐ ᎐ O group at variance with the situation in 4 where both the bipy nitrogen atoms are cis to the oxo ligand.…”

Structural, physico-chemical and antioxidant characteristics of 2,2′-bipyridyl(iminodiacetato)oxidovanadium(IV) dihydrate

“…The crystal structure of the title compound, [VO(IDA)bipy]Á2H 2 O, was originally studied using photographic data at the room temperature with the Cu Ka radiation [31] with P2 1 /a space group, R = 0.0470 and 2h max = 120.0°for the data collection. The present study was undertaken with a CCD diffractometer using the Cu Ka radiation (P2 1 /c space group, R = 0.0342 and 2h max = 134.94°), and resulted in improved geometrical parameters such as precision of bonds lengths as well as valence and torsion angles.…”
