Compared with borates, carbonates, nitrates and phosphates, sul.ates have been ignored as nonl.near optical.Nl.) material. for a l.ng time. Recentl., researchers started to real.ze sul.ates which have the potential.as Nl. material., and synthesized some sul.ate Nl. material. by the water sol.tion method and sol.othermal.method. However, al. these sul.ate Nl. material. have the same probl.m of l.w thermal.stabil.ty. Here, we synthesized a new Cs4 Mg6(SO4)8, which crystal.izes in the orthorhombic space group P212121 with a = 9.102, b = 9.955, c = 16.127 ?, v = 1461.3 ?3, Z = 2, F(000) = 1352, μ = 5.777 mm-1, R = 0.0213 and wR = 0.0480. The singl. crystal.structure can be described as a three-dimensional.framework constructed by MgO6 octahedra and SO4 tetrahedra. Rel.vant optical.measurements indicate that Cs4 Mg6(SO4)8 is short-wave ul.raviol.t transparent and has a moderate second harmonic generation response. Theoretical.cal.ul.tions by the CASTEP package reveal.that S–O groups are Nl.-active anionic groups. Significantl., Cs4 Mg6(SO4)8 has high thermal.stabil.ty up to 781 ℃ based on thermal.anal.ses. We bel.eve that our work wil. provide a new strategy for researchers to devel.p new sul.ate short-wave ul.raviol.t Nl. material. of high thermal.stabil.ty.

A series of 2-acyl.β-l.ctam-2-carboxamides was prepared through a tandem Ugi 4 CC/SN cycl.zation of bromoacetic acid, primary amine, aryl.l.oxal. and isocyanide. Al. of them were characterized by NMR, IR, MS and el.mental.anal.sis. Meanwhil., the singl. crystal.of compound 5 a, C_(19)H_(25)Cl._2 O_3, was al.o obtained and determined by X-ray crystal.ography. Crystal.data: tricl.nic system, space group P_1, a = 8.1318(15), b = 11.931(2), c = 12.027(2) ?, α = 67.361(3)°, β = 73.009(3)°, γ = 85.663(3)°, v = 1029.1(3) ?3, Z = 2, F(000) = 388, Dc = 1.178 g/cm3, μ = 0.204 mm^(-1), R = 0.0786 and w R = 0.2212 for 3585 independent refl.ctions(Rint = 0.0214) and 2960 observed ones(I > 2σ(I)). Intermol.cul.r N–H···O stacking interactions contributed to the stabil.ty of the structure. The antitumor abil.ties of 5 were anal.zed with 3-(4,5-dimethyl.hiazol.2-yl.-2,5-diphenyl.etrazo-l.umbromide(MTT) standard method; 5 c stood out as the most potent showing an IC_(50) of 1.70 μmol.l.against human tumor cel. l.nes(HepG2).
