(8), C(H)CH2 (9), C6H2Me3-2,4,6 (13), C6H4Me-4 (14), C6H4OMe-4 (15), C6H4NMe2-4 (16), C6H5 (17); M = Ag: R = C6H2Me3-2,4,6 (18)) are described. These compounds contain monomeric MR entities, which are η2-bonded by both alkyne ligands of the organometallic 3-titanio-1,4-pentadiyne [(η5-C5H4SiMe3)2Ti(C⋮CSiMe3)2] (1). The X-ray structures of 5, 13, and 18 have been solved. Crystals of 5 are monoclinic
化合物[(η5-C5H4SiMe3)2Ti(C⋮CSiMe3)2]MR(简写为[1·MR];M=Cu:R=Me(5)、CH2SiMe3(6)、Et(7))的两条合成路线, nBu (8), C(H)CH2 (9), C6H2Me3-2,4,6 (13), C6H4Me-4 (14), C6H4OMe-4 (15), C6H4NMe2-4 (16), C6H5 (17) ; M = Ag: R = C6H2Me3-2,4,6 (18)) 进行了描述。这些化合物包含单体 MR 实体,它们通过有机金属 3-钛-1,4-戊二炔 [(η5-C5H4SiMe3)2Ti(C⋮CSiMe3)2] (1) 的两个炔烃配体 η2 键合。5、13 和 18 的 X 射线结构已经解决。5 晶体为单斜晶系,空间群 C2/c,a = 19.477(1) A, b = 10.3622(6) A, c = 16.395(1)
