摘要:
                                Triphenyltin chloride-N,N'-ethylenebis(salicylideneiminato)oxovanadium(IV) (1/1), which crystallises from acetonitrile with half a molecule of the solvent, is a heterodinuclear entity that displays an almost linear tin-oxygen-vanadium unit [Sn-O-V = 172.7(2)degrees; Sn-O = 2.382(2), V-O = 1.614(3) Angstrom]. The tin atom shows approximately trigonal bipyramidal coordination in the adduct with the axial sites occupied by the O and Cl atoms. On the other hand, the vanadium atom is in square-pyramidal coordination, and the vanadium-containing moiety is 68% displaced along the Berry pseudorotation pathway from trigonal bipyramidal towards square pyramidal, compared with the 83% mean displacement for [VO(salen)] itself. The corresponding displacements for the vanadium moiety in Ph3SnCl . VO(hap-1,2-pn). 2CH(3)CN are 94% [Sn-O = 2.405(6), V-O = 1.627(6) Angstrom; Sn-O-V = 175.5(3)degrees] and 89% in Ph3SnCl . VO[salen(3-OMe)(2)]. CH3CN [Sn-O = 2.428(2), V-O = 1.625(2) Angstrom; Sn-O-V = 167.5(1)degrees] [H(2)hap-1,2-pn = N,N'-methylmethylenebis(2-phenolatoacetophenoneimine); H(2)salen(3-OMe)(2) = N,N'-ethylenebis(3-methoxysalicylideneimine)]. The [VO(salen)] adduct of N-triphenylstannyl-1,2-benzisothiazol-3(2H)-one 1,1-dioxide has also been synthesised, and characterised by spectroscopic measurements. (C) 1999 Elsevier Science S.A.
