Arya Stark Instructor: Dr. Scott Oliver TA: Yashar Abdollahian Chem 151L, Section 01C Abstract. In this experiment, oxobis(2,4-pentanediono)vanadium(IV) is synthesized from a mixture of vanadium(V) oxide, sulfuric acid, acetylacetone, and ethanol. The reaction took place over heat, and came to completion when the original mixture turned blue. The solution was then filtered, neutralized, and rec...
Two independent mol-ecules of the title solvated complex, [V(C16H14N2O2)O]·CH3OH, also known as [N,N'-bis-(salicyl-idene)ethyl-enedi-amine]-oxidovanadium(IV) or vanadyl salen, crystallize in the asymmetric unit. Each disordered methanol solvent mol-ecule [occupancy ratios 0.678 (4):0.322 (4) and 0.750 (5):0.250 (5)] is linked to a [N,N'-bis-(salicyl-idene)ethyl-enedi-amine]-oxidovanadium(IV) mo...
The V(V) atom in the title compound, [V(C(7)H(6)ClN(2)O)(C(16)H(11)ClN(2)O(3))O]·CH(3)OH, is N,O-chelated by the benzoyl-hydrazidate anion and O,N,O'-chelated by the (benzoyl-hydrazinyl-idene)propionate dianion. The distorted octa-hedral trans-N(2)O(4) coordination geometry is completed by the vanadyl O atom. The mononuclear and solvent mol-ecules are linked by N-H⋯O and O-H⋯O hydrogen bonds ab...
In the title complex, [V(C(13)H(15)NO(3))O(CH(3)O)(CH(3)OH)], the V(V) atom is six-coordinated by a tridentate O,N,O'-donor ligand, derived from the condensation of salicyl-aldehyde and l-isoleucine, a vanadyl O atom, a methano-late O atom and a methanol O atom in a distorted octa-hedral geometry. The asymmetric unit contains two complex mol-ecules. In the crystal, inter-molecular O-H⋯O and C-H...
