N2 - Various zwitterionic carboxylate ligands form MnII coordination polymers with carboxylate and pseudo-halide bridges mixed in different ways. With mono-zwitterions, [Mn(N3)2(L1)(H 2O)]n and [Mn(N3)2(L 2)]n contains 1D chains with (μ-1,1-N 3)(μ-1,3-OCO) and (μ-1,1-N3)2(μ-1,3- OCO) bridges, respectively. With di-zwitterions, [Mn(N3)(L 3)]n(ClO4)n forms a 2D network based on chains with (μ-1,1-N3)(μ-1,3-OCO)2 bridges, whereas [Mn2(X)4(L4)]n· 2nH2O (X = N3 or NCO) are interpenetrating 3D networks based on chains with (μ-1,1-X)2(μ-1,3-OCO) bridges. With a tri-zwitterion, [Mn7(N3)14(OH) 2(L5)(H2O)6]n· 4nH2O is a 2D network based on a novel chain in which μ-1,1-N 3- and μ-1,3-OCO-bridged trinuclear motifs and μ3-OH- and μ-1,1-N3-bridged tetranuclear motifs are linked by μ-1,3-N3 and μ3-1,1,3-N3. All compounds exhibit antiferromagnetic interactions, the magnitude of which depends upon the nature and mixing mode of the bridges, and follow the trend (μ-N3)(μ-OCO) < (μ-N3)(μ-OCO)2 < (μ-N3)2(μ-OCO) < (μ-NCO) 2(μ-OCO).
