Two new compounds,[ErAg（INA）2（C2O4）]·2H2O（1）（HINA=nicotinic acid） and [Tb0.8Y0.2Ag2（IN）4·（H2O）5]·NO3·2H2O（2）（HIN=isonicotinic acid）,based on the {Ln2} building units,have been hydrothermally synthesized and characterized by single-crystal X-ray diffraction,infrared spectroscopy,thermal analysis and powder X-ray diffraction（PXRD）.Single-crystal X-ray diffraction data reveal that both compounds crystallized in the low-symmetry triclinic space group P1-.Compound 1 is a 3D heterometallic coordination framework based on {Er2}clusters,oxalate ligands and bridging [Ag（INA）] linkers,while compound 2 consists of 0D [Tb0.8·Y0.2Ag2（IN）4（H2O）5]2 subunits that give a 3D supramolecular structure through hydrogen bond *** photoluminescent properties of both compounds（1 and 2） were studied.

The divergence and continuous evolution of plants and animals contribute to ecological *** and transcription factors(TFs) are key determinants of gene regulation and transcription ***,theevolutionary trajectories and relationships of promoters and TFs are still poorly understood. Here, we conducted extensive analysis of large-scale multi-omics sequences in 420 animal species and 223 plant species spanning nearly a billion years of evolutionary history. Results showed that promoter GC-contentandTFisoelectricpoints,as features/signatures that accompany long biological evolution, exhibited increasing growth in animal cells but a decreasing trend in plant cells. Furthermore, the evolutionary trajectories of promoter and TF signatures in the animal kingdom provided further evidence that Mammalia as well as Aves evolved directly from the ancestor Reptilia. The strong correlation between promoter and TF signatures indicates that promoters and TFs formed antagonistic coevolution in the animal kingdom, but mutualistic coevolution in the plant kingdom. The distinct coevolutionary patterns potentially drive the plant-animal divergence, divergent evolution and ecological diversity.
