(4-Chloro-benzohydrazidato-?N',O)[2-(4-chloro-benzoyl-hydrazinyl-idene-?N,O)-3-phenyl-propionato(2-)-?O]oxidovanadium(V) methanol monosolvate.

ABSTRACT: 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 about a center of inversion, generating a dimer.

Project description:The title compound, C(15)H(13)ClN(2)O(2)·CH(4)O, consists of a 4-chloro-N'-(4-meth-oxy-benzyl-idene)benzohydrazide (CMB) mol-ecule and a methanol mol-ecule of crystallization.

The methanol mol-ecule is linked to the CMB mol-ecule through O-H?O and O-H?N hydrogen bonds. In the crystal, CMB mol-ecules are linked through inter-molecular N-H?O hydrogen bonds, involving the methanol mol-ecule, forming chains propagating along [010].

Crystal structure of {2,2'-[ethyl-enebis(nitrilo-methanylyl-idene)]diphenolato-?(4) O,N,N',O'}oxidovanadium(IV) methanol monosolvate.

Project description: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) mol-ecule by an O-H?O hydrogen bond and to others by C-H?O hydrogen bonds. The resulting extended structure consists of a bilayer of mol-ecules parallel to the ab plane. Despite the fact that solvates are common in complexes derived from substituted analogues of the N,N'-bis-(salicyl-idene)ethyl-enedi-amine ligand, the title solvate is the first one of [N,N'-bis-(salicyl-idene)ethyl-enedi-amine]-oxidovanadium(IV) to be structurally characterized. The two vanadyl species have very similar inter-nal geometries, which are best characterized as distorted square-based pyramidal with the vanadium atom displaced from the N2O2 basal plane by 0.5966?(9)?Å in the direction of the doubly-bonded oxide ligand.
