One-carbon-donor Ligands

Con lexes with other One-carbon-donor Ligands. In the octahedral cation of c/s-[Cr (bipy)2(2-methoxyphenyl)slI,HjO, the two anisyl groups are considered a-bonded to the chromium atom. The mean Cr-C distance is 2.10(1) A, and the mean Cr-N(tranr to carbon) distance [2.16(1) A] is longer than that trans to nitrogen [2.07(1) A].

Congtkxes with other One-carbon-donor Ligands. The dimeric molecule [Mos(CH2SiMe3),] is isostructural with the analogous tungsten compound. It consists of two tetrahedral MofCHjSiMes), units held toother by a Mo-Mo triple bond of 2.167 A. The dimer exhibits approximate 2) symmetry. The average Mo-C(CH ) distance is 2.131 A.
