trans) series [Mo(2)(DAniF)(3)](O(2)C(CH=CH)(n)CO(2))[Mo(2)(DAniF)(3)] (n = 0-4). Several unsymmetrical paddlewheel compounds of the type Mo(2)(DAniF)(3)(O(2)CX) (X = C triple bond CH (3), CH=CH(2) (4), (E)-CH=CH-CH=CH(2) (5)) have also been prepared for comparison to the molecules in which there are linked Mo(2) units. The precursors [Mo(2)(DAniF)(3)(MeCN)(2)](BPh(4)), [1]BPh(4), and Mo(2)(DAniF)(3)Cl(MeCN)
具有两个四键连接的 Mo(2)(4+) 单元 Mo(2)(DAniF)(3) (DAniF = N,N'-di-p-anisylformamidinate) 的化合物,由不同长度的不饱和二羧酸二价阴离子连接制备并研究了它们的光谱和电化学性质。通过二羧酸酯接头识别,这些化合物是马来酸酯 (7)、丙二烯-1,3-二羧酸酯 (10)、顺式、顺式-粘康酸酯 (11)、反式、反式-粘康酸酯 (12)、octa-2,4、 6-trans,trans,trans-hexatriene-1,8-dioate (tamuate, 13), and deca-2,4,6,8-trans,trans,trans,trans-octatetraene-1,10-dioate (texate, 14)。后三个分子完成了五元(全反式)系列 [Mo(2)(DAniF)(3)](O(2)C(CH=CH)(n)CO(2))[Mo(2)
