Two compounds of [dmenH(2)(2+)][M(2)(HCOO)(6)(2-)] (M = Mn(II) and Co(II)), synthesized using N,N'-dimethylethylenediammonium (dmenH(2)(2+)) as the template, possess anionic metal formate frameworks of a novel binodal 6-connected (4(12).6(3))(4(9).6(6)) topology. They are the first coordination examples of this unique network closely related to niccolite and colquiriite and exhibit 3D long-range antiferromagnetic ordering with small spin canting.
