'''Methylcobalamin''' (mecobalamin, MeCbl, or MeB{{sub|12}}) is a [[cobalamin]], a form of [[vitamin B12|vitamin B{{sub|12}}]]. It differs from [[cyanocobalamin]] in that the [[cyanide|cyano group]] at the cobalt is replaced with a [[methyl group]]. Methylcobalamin features an octahedral cobalt(III) centre and can be obtained as bright red crystals. From the perspective of [[coordination chemistry]], methylcobalamin is notable as a rare example of a compound that contains metal–alkyl bonds. [[Nickel]]–methyl intermediates have been proposed for the final step of [[methanogenesis]].</div>FuzzyBot
