Numerical prefixes for multiplication of compound or complex (as in complicated) features are created by adding kis to the basic numerical prefix, with the exception of numbers 2 and 3, which are bis- and tris-, respectively.
Ligands are ordered alphabetically by name and precede the central atom name. The number of ligands coordinating is indicated by the prefixes di-, tri-, tetra- penta- etc. for simple ligands or bis-, tris-, tetrakis-, etc. for complex ligands. For example: [CoCl(NH 3) 5]Cl 2 pentaamminechloridocobalt(3+) chloride where ammine (NH 3)precedes ...
In the following prefixes, a final vowel is normally dropped before a root that begins with a vowel, with the exceptions of bi-, which is extended to bis-before a vowel; among the other monosyllables, du-, di-, dvi-, and tri-, never vary.
Tetrakis[3,5-bis(trifluoromethyl)phenyl]borate is an anion with chemical formula [{3,5-(CF 3) 2 C 6 H 3} 4 B] −, which is commonly abbreviated as [BAr F 4] −, indicating the presence of fluorinated aryl (Ar F) groups. It is sometimes referred to as Kobayashi's anion in honour of Hiroshi Kobayashi who led the team that first synthesised it. [1]
Tris(dimethylamino)gallium dimer, formally bis(μ-dimethylamino)tetrakis(dimethylamino)digallium, is an amide complex of gallium. This compound may be used as a precursor to other gallium complexes. Commercially available, this compound may be prepared from lithium dimethylamide and gallium trichloride. [1]
The pentakis icosidodecahedron is a common geometry for geodesic domes derived from the icosahedron. Buckminster Fuller referred to it as the 2-frequency alternate geodesic subdivision of the icosahedron, because the edges are divided into 2 equal parts and then lengthed slightly to keep the new vertices on a geodesic great circle, creating a polyhedron with two distinct edge lengths and face ...
The scientists looked at a bunch of biomarkers, and found that people who took 1 gram of omega-3 fatty acids daily slowed down their biological aging across several areas by up to four months.
Tetrakis(trimethylsilyl)silane is the organosilicon compound with the formula (Me 3 Si) 4 Si (where Me = CH 3). It is a colorless sublimable solid with a high melting point. The molecule has tetrahedral symmetry. The compound is notable as having silicon bonded to four other silicon atoms, like in elemental silicon.
