制备了2个含有叠氮根和硫氰根配位单元的3,4-双咪唑噻吩(L)的锰(Ⅱ)配位聚合物[Mn(L)(n3)2(H2O)]n(1)和[Mn(L)2(SCn3)2]n(2)并报道了它们的晶体结构。化合物1和2是通过3,4-双咪唑噻吩与四水醋酸锰反应,同时分别引入过量的线性三原子阴离子(n3-和SCn-)以取代醋酸根作为抗衡离子制备而得。单晶结构分析表明1和2具有相同的无限二维链状空间结构,但是由不同的44元的[Mn6(L)4(2n3)2]和36元的[Mn4L4]大环单元结构组成。此外,配位聚合物1中的叠氮根分别采用端基单齿和桥联双齿的配位方式,而配位聚合物2中的硫氰根仅以端基氮原子与Mn(Ⅱ)离子配位。

There has recently been a dramatic renewal of interest in hadron spectroscopy and charm physics. This renaissance has been driven in part by the discovery of a plethora of charmonium-like XYZ states at BESⅢ and B factories, and the observation of an intriguing proton-antiproton threshold enhancement and the possibly related X(1835) meson state at BESⅢ, as well as the threshold measurements of charm mesons and charm baryons. We present a detailed survey of the important topics in tau-charm physics and hadron physics that can be further explored at BESⅢ during the remaining operation period of BEPCⅡ. This survey will help in the optimization of the data-taking plan over the coming years, and provides physics motivation for the possible upgrade of BEPCⅡ to higher luminosity.

Using a dedicated data sample taken in 2018 on the J/ψpeak,we perform a detailed study of the trigger efficiencies of the BESIII *** efficiencies are determined from three representative physics processes,namely Bhabha scattering,dimuon production and generic hadronic events with charged *** combined efficiency of all active triggers approaches 100%in most cases,with uncertainties small enough not to affect most physics analyses.

Studies of e^+e~→D_s^+■^((*)0)K^-and the P-wave charmed-strange mesons are performed based on an e^+e^-collision data sample corresponding to an integrated luminosity of 567 pb^(-1) collected with the BESIII detector at s^(1/2)=4.600 Gev. The processes of e^+e^-→D_s^+■^(*0)K^- and D_s^+■~0K^- are observed for the first time and are found to be dominated by the modes D_s^+D_(s1)(2536)^-and D_s^+D_(s2)~*(2573)^-, respectively. The Born cross sections are measured to be σ~B(e^+e^-→D_s^+■^(*0)K^-) =(10.1±2.3±0.8) pb and σ~B(e^+e^-→D_s^+■~0K^-) =(19.4±2.3± 1.6) pb, and the products of Born cross section and the decay branching fraction are measured to be σ~B(e^+e^-→D_s^+D_(s1)(2536)^-+c.c.)·B(D_(s1)(2536)^-→■^(*0)K^-)=(7.5±1.8±0.7) pb and σ~B(e^+e^-→D_s^+D_(s2)~*(2573)^-+ c.c.)·B(D_(s2)~*(2573)^-→■~0 K^-)=(19.7 ± 2.9 ±2.0) pb. For the D_(s1)(2536)^-and D_(s2)~*(2573)^-mesons, the masses and widths are measured to be M(D_(s1)(2536)^-)=(2537.7±0.5 ±3.1) Mev/c2, Γ(D_(s1)(2536)^-) =(1.7 ±1.2 ±0.6)Mev, and M(D_(s2)~*(2573)^-)=(2570.7±2.0 ±1.7) Mev/c^2, Γ(D_(s2)~*(2573)^-)=(17.2 ±3.6 ±1.1) Mev. The spin-parity of the D_(s2)~*(2573)^-meson is determined to be J^p= 2^+. In addition, the processes e^+e^-→D_s^+■^((*)0)K^-are searched for using the data samples taken at four(two) center-of-mass energies between 4.416(4.527) and 4.575 Gev, and upper limits at the 90% confidence level on the cross sections are determined.
