New tetrahedrane complexes from molybdenum alkynyls and Co2(CO)8
摘要:
The molybdenum alkynyl complexes [Mo(Cequivalent toCPh)(eta(3)-allyl)(CO)(2)(bipy)] (1) and [Mo(Cequivalent toCH)(eta(3)-allyl)(CO)(2)(N-N)] (N-N=2,2'-bipyridine. 2a: 1,10-phenanthroline. 2b) react with dicobalt octacarbonyl to give the new tetrahedrane trimetallic complexes [Co-2(CO)(6)(mu-eta(2):eta(2)-M-Cequivalent toCPh)], M = {Mo(eta(3)-C3H5)(CO)(2)(bipy)} (3) and [Co-2(CO)(6)(mu-eta(2):eta(2)-M-Cequivalent toCH)]. M={Mo(eta(3)-C3H5)(CO)(2)(N-N)} (N-N = bipy. 4a: phen. 4b), respectively. These new compounds were characterized by analytical (C, H, N). spectroscopic (IR. H-1 NMR) and crystallographic (single crystal X-ray diffraction) means. (C) 2003 Elsevier Science B.V. All rights reserved.
