摘要：

From Me3SiC=C-C=CSiMe3 and Ph2PC=C-C=CPPh2 diynes and vanadocene VCp2, homobimetallic vanadium d(1)-d(1) complexes are synthesized and characterized by X-ray crystal structures of (Cp2V)(2)(1-2 eta:3-4 eta-RC=C-C=CR), (R = SiMe3 1 PPh2 2); magnetic moments of both complexes from 300 to 2 K indicate an antiferromagnetic J exchange coupling of -10.5 and -59.8 cm(-1) for 1 and 2, respectively.
