[Cu(dmtu)3]2I2 has a centrosymmetric dimeric cation with two uncoordinated iodides, four terminal dmtu and two doubly bridging dmtu ligands, [(dmtu)2Cu(μ-S-dmtu)2Cu(dmtu)2]I2. A reversal of this monomer to dimer trend from bromide to iodide is seen for the etu counterparts: [BrCu(etu)2]2 is a centrosymmetricdimer with two doubly bridging etu ligands, [(etu)BrCu(μ-S-etu)2CuBr(etu)], whereas [ICu(etu)2] is a trigonal
Synthesis and photolysis of mixed copper(I) complexes with thiones and tri-p-tolylphosphine or triphenylphosphine; X-ray crystal structure of bis[copper(I)(1,3-thiazolidine-2-thione) (tri-p-tolylphosphine)chloride]
(L) yields binuclear complexes of the general formula [Cu(PR3)(L)Cl]2 [L = 1,3-thiazolidine-2-thione (tzdtH), benz-1,3- thiazoline-2-thione (bztztH), dithiouracil (dtu), purine-6-thione (pur6SH) and thiourea (tu)]. Irradition of the complexes, in chloroform, methanol and acetonitrile solutions, caused phosphine evolution while the Cu2S2 core remained intact. The crystalstructure of [Cu(tptp)(tzdtH)Cl]2
[Cu(PR 3)Cl] 4 [其中PR 3 =三-对甲苯基膦(tptp)或三苯基膦(tpp)]与几种杂环硫酮(L)的反应生成通式为[Cu(PR 3)的双核配合物)(L)Cl] 2 [L = 1,3-噻唑烷-2-硫酮(tzdtH),苯并1,3-噻唑啉-2-硫酮(bztztH),二硫尿嘧啶(dtu),嘌呤-6-硫酮(pur6SH )和硫脲(tu)]。在氯仿,甲醇和乙腈溶液中辐照配合物会导致磷化氢放出,而Cu 2 S 2核保持完好无损。[Cu(tptp)(tzdtH)Cl] 2的晶体结构已通过单晶X射线衍射法确定。在铜2 S 2核的CuS键长为2.386(1)和2.470(1)。CuP和CuCl的距离分别为2.222(1)和2.283(1)。
A Breakthrough Efficiency of 19.9% Obtained in Inverted Perovskite Solar Cells by Using an Efficient Trap State Passivator Cu(thiourea)I
the trap states of perovskite to achieve high-performanceperovskitesolarcells (PSCs). Here, we have first revealed and demonstrated that a novel p-type conductor Cu(thiourea)I [Cu(Tu)I] incorporated in perovskitelayer can effectively passivate the trap states of perovskite via interacting with the under-coordinated metal cations and halide anions at the perovskite crystal surface. The trap state energy

depending on whether the water of crystallisation is present or absent. The structure of bis(μ-thiourea)tetrakis(thiourea)dicopper(I) dichloride dihydrate, [Cu2(tu)6]Cl2 · 2H2O (1) was determined at room and also at low temperature. Bis(μ-thiourea)tetrakis(thiourea)dicopper(I) dibromide dihydrate, [Cu2(tu)6]Br2 · 2H2O (2) is isomorphous with 1, like the anhydrous compounds chlorotris(thiourea)copper(I), [Cu(tu)3]Cl
