摘      要：Five novel SrⅡ-LnⅢ heterometallic coordination polymers based on pyridine-2,6- dicarboxylic acid （H2pda） and imidazole （im）, namely, [LnSr（pda）3（H2O）5]-Him·C2H5OH·3H2O （Ln = Nd （1）; Pr （2））, [Ln2Sr（pda）6（H2O）5]-4Him·C2H5OH·5H2O （Ln = Nd （3）; Pr （4））, and [ErSr（pda）3（H2O）4].Him-3.5H2O （5）, have been prepared and structurally characterized. X-ray crystallographic analyses revealed that these complexes display three varieties of l-D chain structures. Several types of hydrogen bonding interactions are found for 1-5, which connect the 1 -D chain structures to form 2-D suoramolecular networks.
