Tm Class
By replacing the nitrogen donor of a Tp ligand atoms with sulfur atoms, a class of ligands known as Tm can be made. These are related to the thioureas.ยน; Several research groups including Anthony F. Hill's group have been working on this ligand class. To form NaTm {Na+ HB(mt)3-), Methimazole and sodium borohydride are heated together.
Coordination chemistry with ruthenium, rhodium, osmium, molybdenum, tungsten, and other metals has been reported.

Famous quotes containing the word class:
“The enemy are no match for us in a fair fight.... The young men ... of the upper class are kind-hearted, good-natured fellows, who are unfit as possible for the business they are in. They have courage but no endurance, enterprise, or energy. The lower class are cowardly, cunning, and lazy. The height of their ambition is to shoot a Yankee from some place of safety.”
—Rutherford Birchard Hayes (1822–1893)
