报道了配合物[Et3NH]2[V(Cat)3]‘CH3CN，K3[V(Cat)3]-1.5H20和K2[VO(Cat)2]··20的合成、性质和晶体结构。配合物[Et3NH]2[V(Cat)3]-CH3CN LP2{2{2i，a=10.473(1)，b=10.794(1)，c-29.986(3)α；Z=4；p^=1.216；pobsd=1.21g cm-3；RW=7.2%]由一个新的钒(IV)八面体配合物[VO键长1.930(3)α；OVO键角88.8]组成。相反，K2[V0(Cat)2]-Et0H-H20[P2，/c，a=14.380(1)，b=12.307(2)A，c=11.187(1)A，？配合物K3[V(Cat)3]-1.5H20[C2/c，a=20.727(4)A，b=15.884(2)A，c=12.312(2)A，？W=4.6%]非常接近金属的八面体对称性，与铬和铁的类似物是等结构的。
The syntheses, properties, andcrystal structures of the complexes [Et3NH] 2 [V (cat) 3]'CH3CN, K3 [V (cat) 3]-1.5 H20, and K2 [VO (cat) 2]·· 20 are described. The complex [Et3NH] 2 [V (cat) 3]-CH3CN lP2 {2 {2i, with a= 10.473 (1) Á, b= 10.794 (1) Á, and c— 29.986 (3) Á; Z= 4; p^^= 1.216; pobsd= 1.21 g cm'3; Rw= 7.2%] consists of a novel vanadium (IV) octahedral complex [VO bond length 1.930 (3) Á; OVO bond angle 88.8] in which catechol has displaced the vanadyl oxygen. In contrast, K2 [V0 (cat) 2]-Et0H-H20 [P2,/c with a= 14.380 (1) Á, b= 12.307 (2) A, and c= 11.187 (1) A, ß= 111.80; Z= 4; pcMci= 1.537; j? w= 7.8%] is a typical square-pyramidal vanadyl complex; V= 0 bond length of 1.616 (4) A, the vanadium 0.58 A out of the basal plane, and average VO (catechol) bond lengths of 1.956 A. The complex K3 [V (cat) 3]-1.5 H20 [C2/c, with a= 20.727 (4) A, b= 15.884 (2) A, c= 12.312 (2) A, and ß= 91.46; Z= 8; Pcalcd= 1.703; 7? w= 4.6%] closely approximates octahedral symmetry about the metal and is isostructuralwith the Cr and Fe analogues.
