Reaction of MnSO 4 · H 2 O, 2,2′‐bipyridine (bpy), suberic acid and Na 2 CO 3 in CH 3 OH/H 2 O yielded a mixture of [Mn 2 (H 2 O) 4 (bpy) 2 (C 8 H 12 O 4 ) 2 ] · 2 H 2 O ( 1 ) and [Mn(H 2 O) 2 ‐ (bpy)(C 8 H 12 O 4 ) 2/2 ] · H 2 O ( 2 ). In both complexes, the Mn atoms are octahedrally coordinated by two N atoms of one bpy ligand and four O atoms of two trans positioned H 2 O molecules and two suberato ligands (d(Mn–O) = 2.107–2.328 Å; d(Mn–N) = 2.250–2.330 Å). The bis‐monodentate suberato ligands bridge Mn atoms to form dinuclear [Mn 2 (H 2 O) 4 (bpy) 2 (C 8 H 12 O 4 ) 2 ] complex molecules in 1 and 1D $^1_\infty$ [Mn(H 2 O) 2 (bpy)(C 8 H 12 O 4 ) 2/2 ] chains in 2 . Via the intermolecular hydrogen bondings and π‐π stacking interactions, the dinuclear molecules in 1 are assembled into 2D networks parallel to (100), between which the crystal H 2 O molecules are sandwiched. The polymeric chains in 2 are linked together by interchain hydrogen bonding and π‐π stacking interactions into 3D networks with the crystal H 2 O molecules located in tunnels along [010]. Crystal data for 1 : P 2 1 / c (no. 14), a = 10.092(1) Å, b = 11.916(2) Å, c = 17.296(2) Å, β = 93.41(1)° and Z = 2. Crystal data for 2 : P 2 1 / c (no. 14), a = 11.176(2) Å, b = 9.688(1) Å, c = 37.842(6) Å, β = 90.06(1)° and Z = 8.
