Pentamethylmolybdenum is an organomolybdenum compound containing five methyl groups bound to a central molybdenum atom. [2] The shape of the molecule is a square pyramid. [3]
Pentamethylmolybdenum can be prepared from molybdenum pentachloride and dimethyl zinc at low temperature between −70 and −20. Another possible creation route, is from molybdenum oxychloride. [2] Pentamethylmolybdenum is paramagnetic with one unpaired electron. The character of this electron is two thirds 4dz2 and one third 4dx2−y2. [2]
Pentamethylmolybdenum is unstable and sensitive to oxygen. It turns black when exposed to air, or heated over −10°C. [2] The Raman spectrum has bands at 1181, 960, 90, 882, 783, 672, 620, 565, 523, 507, 451, 366, 308, 267 and 167 cm−1. [2]
