Bmet, bmpp and bmbu all form mononuclear complexes with first-row transition metal ions (Co3+, Fe2+, Ni2+, Mn2+), and X-ray structures of [Mn(bmet)](ClO4)2, [Ni(bmet)](ClO4)2, [Fe(bmet)](ClO4)2, [Mn(bmpp)](ClO4)2·2MeCN and [Co(bmpp)](ClO4)3·H2O are reported. As the aliphatic methylene chain increases in length, formation of dinuclear, and in some cases trinuclear, complexes becomes more pronounced
