摘要：

The Schiff-base dianion N,N'-2,2-dimethyltrimethylenebis[salicylideneiminate(2-)](salnptn) coordinates to vanadium(IV) to form [VO(salnptn)] whose crystal structure has been determined. The compound is polymeric in the solid state with ... V=O --> V=O --> V=O ... chains, the salnptn donor atoms being coplanar and the salnptn framework umbrella-shaped. In the derivative [VO(OMe) (salnptn)], the crystal structure of which has also been determined. the OMe and the vanadyl oxygen are co-ordinated cis to each other, and the salnptn now occupies three equatorial and one axial co- ordination positions. Even N,N'-ethylenebis(salicylideneiminate) seems to behave analogously, though it is normally planar.
