Definition of Pentacoordinate. Meaning of Pentacoordinate. Synonyms of Pentacoordinate

- phenomenon in which electronegative substituents of trigonal bipyramidal pentacoordinate compounds prefer to occupy apical (axial) positions (Lap). The term...
- generally true of pentacoordinated main-group elements with one or more lone-pair-containing ligand, including the oxygen-pentacoordinated silicon examples...
- acidity function. It even protonates some hydro­carbons to afford pentacoordinate carbo­cations (carbonium ions). Like its precursor hydrogen fluoride...
- single electron donating atom of the protein, the iron is often in a pentacoordinate state. When oxygen or the toxic carbon monoxide is bound the iron becomes...
- bridged by hydroxyl group (A). One iron is hexacoordinate and another is pentacoordinate. A hydroxyl group serves as a bridging ligand but also functions as...
- such as THF to give hexacoordinated adducts. Bulkier ligands (L) give pentacoordinated adducts TiCl4L. TiCl4 is produced by the chloride process, which involves...
- its parent molecule CH4, methane. While nonrigidity is common for pentacoordinate species, six-coordinate species typically adopt a more rigid octahedral...
- phosphate. The metal ions occupy both octahedral (six-coordinate) and pentacoordinate sites in a 1:2 ratio. Magnesium phosphate tribasic is listed on the...
- ethylene glycol and an alkali metal base to produce highly reactive, pentacoordinate silicates which provide access to a wide variety of new silicon compounds...
- been identified in complexes with organosilicon compounds containing pentacoordinate palladium; see Shimada, Shigeru; Li, Yong-Hua; Choe, Yoong-Kee; Tanaka...
