“…In addition, since the cluster-bonded ligand is capable of interacting with several metal centers, it frequently displays a reactivity different from that found in the monometallic systems [5][6][7][8][9]. We have prepared the heptafunctional molecule (Ph 2 P(o-C 6 H 4 )CH@NCH 2 CH 2 ) 3 N [10] and shown its coordination chemistry with tungsten carbonyls to generate a novel cryptand-like metallatricycle complex.…”
