catena-Poly[[aqua­dioxidouranium(VI)]-μ3-4,4′-oxydibenzoato]

The title compound, [UO(2)(C(14)H(8)O(5))(H(2)O)](n), is a polymeric UO(2) complex bridged by 4,4'-oxydibenzoate ligands. One carboxyl-ate group of the bridging ligand chelates a uranyl cation while the other carboxyl-ate group of the ligand bridges two other two uranyl cations, forming a double-chain polymeric structure. The central U(VI) atom is seven-coordin-ated in a distorted UO(7) penta-g...

Osmium(vi) Complexes of Sulphonyl Amid0 Ligand. Crystal Structures Of

Interactions of [PPh4]2[0s02C14] and [Bu”,Nl[OsNCl~] with LiZL [H2L = 1,2bis(p-toluenesulphonylamido)benzene] gave binuclear osmium(V1) compounds (PPh,),[Osz 04LZ(p-OH)d (1) and OS~N~L&-OH)~ (2), respectively. The structures of both compounds have been determined by X-ray crystallography. The crystal structure of the [OsZ04LZ@0H),12anion contains two trans-0s02(L) units bridged by two OH groups...

On the possible volume of $mu$-$(v,k,t)$ trades

‎A $mu$-way $(v,k,t)$ $trade$ of volume $m$ consists of $mu$‎ ‎disjoint collections $T_1$‎, ‎$T_2‎, ‎dots T_{mu}$‎, ‎each of $m$‎ ‎blocks‎, ‎such that for every $t$-subset of $v$-set $V$ the number of‎ ‎blocks containing this t-subset is the same in each $T_i (1leq‎ ‎i leq mu)$‎. ‎In other words any pair of collections ${T_i,T_j}$‎, ‎$1leq i< j leq mu‎$ is a $(v,k,t)$ trade of volume $m$. In th...

Crystal structure of catena-poly[[[tri­aqua­strontium]-di-μ2-glycinato] dibromide]

In the title coordination polymer, {[Sr(C2H5NO2)2(H2O)3]Br2} n , the Sr(2+) ion and one of the water mol-ecules are located on twofold rotation axes. The alkaline earth ion is nine-coordinated by three water O atoms and six O atoms of the carboxyl-ate groups of four glycine ligands, two in a chelating mode and two in a monodentate mode. The glycine mol-ecule exists in a zwitterionic form and br...
