Tungsten Hexacarbonyl Picture Inquiry & Feedback

Brief Introduction

Tungsten hexacarbonyl is a coordination compound with the chemical formula W(CO)6. Through it, the first dihydrogen complex was obtained. It is a colorless solid, and is the same as the carbonyl chromium hexacarbonyl and molybdenum hexacarbonyl, which is a volatile and stable substance in the air, in which the tungsten atom has a zero valence.
