摘要：
The reaction of Co-4(CO)(12) with the dipropargylamine [(HC=CCMe2)(2)NMe] (ligand A) leads to moderate yields of the title complex (complex 4). An X-ray analysis has shown that this tetranuclear complex is a 'spiked' (or metallo-ligated) triangular cluster containing one molecule of ligand A partially cyclized and coordinated to all four metal atoms. Complex 4 is the first tetracobalt cluster showing this type of structure which was previously found only for two M2Ni2 (M = Fe, Ru) isopropenylacetylene derivatives. Reaction pathways leading to the formation of complex 4 are discussed. (C) 2002 Elsevier Science B.V. All rights reserved.
