Synthesis, Single Crystal X-Ray Structure, Hirshfeld Surface Analysis of a New Isopolymolybdate Based Supramolecular Hybrid

摘要

Design and synthesis of supramolecular hybrids with low dimensionality is currently an attractive research topic. The reaction of Schiff base metal complex with isopolymolybdate leads to the isolation of a new isopolymolybdate based supramolecular hybrid, [Mn(salen)(H_2O)_2]_2[Mo_8O_(26)]Na_2·2H_2O (1) (salen = N,N'-bis(salicylidene)ethylenediamine). The supramolecular hybrid was characterized by single crystal X-ray structure analyses, elemental analyses and X-ray crystallography. Crystal data for 1: triclinic, P-1, a=10.0206(8)?, b = 11.7416(10)?, c= 13.1494(13)?, V = 1382.8(2)?~3, Z= 1, R_(gt)(F) = 0.0353 and wR_(ref)(F~2) = 0.1009. Structural analyses reveal that 1 represents the first example of [Mo_8O_(26)]~(4-) chains formed POM-Schiff-base hybrid. Hirshfeld surface analysis and fingerprint plots are used for decoding intermolecular interactions in 1. Additionally, magnetic property of 1 indicates that there is an antiferromagnetic coupling between the metal centers in the complex.
