Two dinuclear Fe(Ⅱ)complexes Fel(NCS)×2DMF×2HO(1)and Fel(NCSe)4×2DMF×2HO(2)have been designed and prepared based on ligand 1-naphthylimino-1,2,4-triazole(l).Single-crystal structural analyses at 298 K identified that the dinuclear complex contains two iron(II)ions in the high spin(HS)state for 1 and *** Fe(Ⅱ)ions in 1 and 2 were low spin(lS)state at 90 K by comparison with the

The underlying physics of QCD phase transition in the early Universe remains largely unknown due to its strong-coupling nature during the quark-gluon plasma/hadron gas transition, yet a holographic model has been proposed to quantitatively fit the lattice QCD data while with its duration of the first-order phase transition(FoPT) left undetermined. At specific baryon chemical potential, the first-order QCD phase transition agrees with the observational constraint of baryon asymmetry. It, therefore, provides a scenario for phase transition gravitational waves(GWs) within the standard model of particle physics. If these background GWs could contribute dominantly to the recently claimed common-spectrum red noise from pulsar timing array(PTA) observations, the duration of this FoPT can be well constrained, and the associated primordial black holes are still allowed by current observations.
