Abstract
Two novel metal−organic frameworks [Ni7(H2O)6L2(O)2](Cl)2(NO3)2·6(H2O)·(Emim)2 (1) and [Ni2(H2O)2L]·7(H2O) (2) have been successfully constructed by using ionothermal and hydrothermal synthesis, respectively. Compound 1 represents the new type metal−organic replicate of PoCl2 with the scu net containing an eight-connecting polynuclear cluster and a large four-connecting complex. Compound 2 showing a one-dimensional chain has been separated in a traditional hydrothermal method using similar starting materials. By inspection of the structures of 1 and 2, it is believed that the different reaction conditions play important roles in forming the final structures. In addition, we investigated the optical band gap of compound 1.
