Crystal structure and EPR spectra of (Bu4N)2[V(dmit)3]

Аннотация

The tris-chelate complex of vanadium(IV) (Bu₄N)₂[V(dmit)₃] is prepared from VCl₃ and (Bu₄N)₂[Zn(dmit)₂] (dmit = isotrithionedithiolate C₃S₅^2–) and characterized by single crystal XRD and mass spectrometry. The complex crystallizes in the space group Pna2₁ and has a distorted octahedral environment of vanadium. The complex is paramagnetic and gives a characteristic EPR spectrum in both solution and solid phase. The g factors and hyperfine interaction constants are determined.
