Preparation and Characterization of Ti(BH4)3(THF)3 and V(BH4)2(TMEDA)2 Complexes
We have recently synthesized Ti(BH4)3(THF)3 and V(BH4)2(TMEDA)2 complexes. The reaction of TiCl3(THF)3 with NaBH4 in dry THF gave flat blue crystals, Ti(BH4)3(THF)3. The reaction of VCl3 with NaBH4 in presence of N, N, N', N'- tetramethyle...
متن کاملMethoxo[N′-(3-methoxy-2-oxidobenzylidene)benzohydrazidato]oxidovanadium(V)
In the title complex, [V(C(15)H(12)N(2)O(4))(CH(3)O)O], the V(V) ion exhibits a distorted square-pyramidal coordination geometry; three donor atoms from a hydrazone ligand and one O atom of the deprotonated methanol define the coordination basal plane. The V(V) ion is displaced by 0.464 (1) Å from the basal plane towards the axial oxide O atom. Intra-molecular O-H⋯N hydrogen bonding occurs. Int...
متن کامل[N′-(3-Ethoxy-2-oxidobenzylidene-κO 2)-4-methylbenzohydrazidato-κ2 O,N′](methanolato-κO)oxidovanadium(V)
The title oxidovanadium(V) complex, [V(C(17)H(16)N(2)O(3))(CH(3)O)O], was obtained by the reaction of 3-eth-oxy-2-hy-droxy-benzaldehyde, 4-methyl-benzohydrazide and vanadyl sulfate in methanol. The V(V) atom is coordinated by the O,N,O'-tridentate Schiff base ligand, one methano-late O atom and one oxide O atom, forming a distorted VO(4)N square-pyramidal coordination geometry. The oxide O atom...
متن کامل(Methanolato-κO)[N′-(3-methoxy-2-oxidobenzylidene-κO 2)-4-nitrobenzohydrazidato-κ2 N′,O]oxidovanadium(V)
The title oxidovanadium(V) complex, [V(C(15)H(11)N(3)O(5))(CH(3)O)O], was obtained by the reaction of 2-hy-droxy-3-meth-oxy-benzaldehyde, 4-nitro-benzohydrazide and vanadyl sulfate in methanol. The V(V) atom is five-coordinated by the two O and one N donor atoms of the Schiff base ligand, one methano-late O atom and one oxido O atom, forming a distorted square-pyramidal geometry.
متن کامل(Ethanolato-κO)[N′-(3-methoxy-2-oxidobenzylidene-κO 2)benzohydrazidato-κ2 N′,O]oxidovanadium(V)
In the title complex, [V(C(15)H(12)N(2)O(4))(C(2)H(5)O)O], the V(V) ion is coordinated by an oxide O atom, an ethano-late anion and two O atoms and one N atom from the tridentate benzo-hydrazidate dianion in a distorted square-pyramidal geometry; the V atom is displaced by 0.4748 (8) Å from the basal plane towards the axial oxide O atom. An intra-molecular O-H⋯N hydrogen bond occurs in the benz...
