'''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]].
'''メチルコバラミン'''('''Methylcobalamin''', メコバラミン、MeCbl、MeB{{sub|12}})は、[[Vitamin B12|ビタミンB{{sub|12}}]の一種である[[cobalamin/ja|コバラミン]]である。] コバルトの[[cyanide/ja|シアノ基]][[methyl group/ja|メチル基]]に置換されている点で[[cyanocobalamin/ja|シアノコバラミン]]とは異なる。メチルコバラミンは八面体のコバルト(III)中心を持ち、明るい赤色の結晶として得られる。 [[coordination chemistry/ja|配位化学]]の観点からは、メチルコバラミンが金属-アルキル結合を含む化合物の珍しい例として注目される。[[Nickel/ja|ニッケル]]-メチル中間体は、[[methanogenesis/ja|メタン生成]]の最終段階として提案されている。
