The structure of M₂(OH)₂(bpdc) (bpdc = biphenyl dicarboxylate, C₁₄H₈O₄) is distinct from that of the isoreticular compounds M₂(OH)₂(bdc) (bdc = benzene dicarboxylate, C₈H₄O₄) (M = Mn, Fe), in the sense that no disorder of the bpdc molecules from one layer to the other needs to be considered. The global symmetry is lower in the bpdc compounds (P1) than in the bdc compounds (C2/m). Both Mn₂(OH)₂(bpdc) and Fe₂(OH)₂(bpdc) order magnetically at 36.8 and 46.5 K, respectively, and can be considered as uncompensated antiferromagnets, whereas Mn₂(OH)₂(bdc) (Néel temperature T_N = 38.5 K) and Fe₂(OH)₂(bdc) (T_N = 66 K) are compensated antiferromagnets.

层状杂化有机-无机化合物 M2(OH)2(C14H8O4) (M = Mn, Fe) 的晶体结构和磁性

的结构中号₂（OH）₂（BPDC）（BPDC =联苯二羧酸酯，C ₁₄ H ^ ₈ ö ₄）是不同于所述isoreticular化合物的中号₂（OH）₂（BDC）（BDC =苯二羧酸酯，C ₈ H ₄ O ₄ ) ( M = Mn, Fe)，从某种意义上说，不需要考虑 bpdc 分子从一层到另一层的无序。bpdc 化合物 ( P 1 )的全局对称性低于 bdc化合物 ( C 2/ m )。Mn ₂ (OH) ₂(bpdc) 和 Fe ₂ (OH) ₂ (bpdc) 分别在 36.8 和 46.5 K 处磁性排列，可以被认为是未补偿的反铁磁体，而 Mn ₂ (OH) ₂ (bdc)（Néel 温度T _N = 38.5 K）和 Fe ₂ (OH) ₂ (bdc) ( T _N = 66 K) 是补偿反铁磁体。
