OSTI.GOV Journal Article: Coordination compounds of a number of d and f metals with amide ligands

Coordination of 2 a to the metal center causes a dissociation of the diphenylmethoxy moiety in 5 aa, thereby forming 7 aa, which undergoes an amine exchange reaction with HN(SiHMe 2) 2 to afford the double‐hydrosilylated product HN[Si(OCHPh 2)Me 2] 2 along with 8 aa.

The amide coordination of even one of the three crystallographically independent LH − ligands is enough to lead to an 1D coordination polymer and, thus, complex 1 becomes the first example of a polymeric succinamato(−1) complex of any metal. OSTI.GOV Journal Article: Amide coordination effects in organolithiums. Amide coordination effects in organolithiums. Full Record; Other Related Research Here we report a precise control of isolated single ruthenium site supported on nitrogen-doped porous carbon (Ru SAs/N–C) through a coordination-assisted strategy. This synthesis is based on the utilization of strong coordination between Ru3+ and the free amine groups (−NH2) at the skeleton of a metal–organic framework, which plays a critical role to access the atomically isolated dispersion of Ru sites. In this Minireview, the fate of amine–boranes upon coordination to a metal center is discussed with a particular emphasis on B H activation pathways.

Metal amide coordination

2009-09-01 oxygen donors. One must note that the amide nitrogen is completely non-basic and does not coordinate to metal ions unless it is deprotonated (Figure 2). Coordination occurs through the carbonyl oxygen of the amide group. A literature review of structures of amide complexes of metal ions was carried out Metal amides (systematic name metal azanides) are a class of coordination compounds composed of a metal center with amide ligands of the form NR 2 −.Amide ligands have two electron pairs available for bonding. In principle, they can be terminal or bridging.
