A series of novel manganese 
,
-dicarboxylates, Mn2(H2O)[O2C(CH2)nCO2]2 (n = 3-12),were synthesized as single crystals or polycrystallines by the hydrothermal reaction of MnCl2with the corresponding dicarboxylic acid in the presence of base. Mn2(H2O)[O2C(CH2)3CO2]2and Mn2(H2O)[O2C(CH2)5CO2]2 (n = 3 and 5) crystallized in the orthorhombic space groupPbcm (No. 15), with a = 7.6701(6) Å, b = 9.1156(4) Å, c = 17.975(1) Å, and Z = 4 and witha = 7.6089(8) Å, b = 9.167(2) Å, c = 23.070(3) Å, and Z = 4, respectively. Using various,-dicarboxylates with different numbers of carbons in alkyl chains, the interlayer spacingsof the manganese(II) compounds have been varied from 8.99 to 20.42 Å. Their organic chainsbetween two terminal carboxylates are close-packed and self-assembled between Mn-Olayers. The relative conformations of two terminal carboxylate groups determine the spacinggroups of crystal structures. All the prepared manganese dicarboxylate compounds involvethe replication of the local crystal structure in the Mn-O monolayer to present anantiferromagnetic interaction.
