摘要：

The structure of M-2(OH)(2)(bpdc) (bpdc = biphenyl dicarboxylate, C14H8O4) is distinct from that of the isoreticular compounds M-2(OH)(2)(bdc) (bdc = benzene dicarboxylate, C14H8O4) (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 (P (1) over bar) than in the bdc compounds (C-2/m). Both Mn-2(OH)(2)(bpdc) and Fe-2(OH)(2)(bpdc) order magnetically at 36.8 and 46.5 K, respectively, and can be considered as uncompensated antiferromagnets, whereas Mn-2(OH)(2)(bdc) (Ne ' el temperature T-N = 38.5 K) and Fe-2(OH)(2)(bdc) (T-N = 66 K) are compensated antiferromagnets.
