Abstract: The title compounds, bis(dimethylformamide)-1 [bold kappa] O,3O-bis{ [bold mu] -2,2'-[2,2'-dimethylpropane-1,3-diylbis(nitrilomethylidyne)]diphenolato}-1⁴N,N',O,O':2²O,O';2²O,O':3⁴N,N',O,O'-di--nitrito-1:2²N:O;2:3²O:N-dinickel(II)cobalt(II), [CoNi₂(NO₂)₂(C₁₉H₂₂N₂O₂)₂(C₃H₇NO)₂], (I), -copper(II), [CuNi₂(NO₂)₂(C₁₉H₂₂N₂O₂)₂(C₃H₇NO)₂], (II), and -manganese(II), [MnNi₂(NO₂)₂(C₁₉H₂₂N₂O₂)₂(C₃H₇NO)₂], (III), consist of centrosymmetric linear heterotrinuclear metal complexes. The three complexes are isostructural. There are three bridges across the Ni-M atom pairs (M is Co²⁺, Cu²⁺ or Mn²⁺) in each complex, involving two O atoms of a [bold mu] -N,N'-bis(salicylidene)-2,2'dimethyl-1,3-propanediaminate ligand and an N-O moiety of a -nitrito group. The coordination sphere around each metal atom, whether Co²⁺, Cu²⁺, Mn²⁺ or Ni²⁺, can be described as distorted octahedral. The NiM distances are 2.9988 (5) Å in (I), 2.9872 (5) Å in (II) and 3.0624 (8) Å in (III).
