Three new complexes constructed by 1-adamantaneacetic acid (HL), [Zn2L4]n (1), [MnL2(4,4'-bipy)(H2O)2]n? 2n(HL) (2) and MnL2(2,2'-bipy)(H2O)2 (3), have been hydrothermally synthesized. X-ray single crystal diffraction analyses reveal that both 1 and 2 are infinite 1D chains along b axis. 2 and 3 have an octahedral coordination and show the supramolecular structures which are formed on the basis of the connectivity of intermolecular hydrogen bonds. The deprotonated L－ ligands coordinate the M(II) atoms with many coordination modes in the title complexes.
