Triple bridged anionic dimetallic complexes from cis-[Mo(η3-methallyl)Cl(CO)2(NCMe)2] and pyrazolates
摘要:
The reactions of cis-[Mo(eta(3)-methallyl)Cl(CO)(2)(NCMe)(2)] and 0.5 equivalents of tetra-n-butylammonium salts of pyrazolate (pz), 3,5-dimethylpyrazolate (dmpz) or indazolate (inz) lead to (NBu4)-Bu-n[{Mo(eta(3)-methallyl)(CO)(2)(mu-Cl)}(2)(mu-pz*)] (pz* = pz, dmpz, inz), where the bridging pyrazolato is coordinated trans to the allyl group and both bridging chlorido ligands are coordinated trans to the carbonyls.
