چکیده
/ac-L i4[R h(S03)3(0 H 2)3](0H ) crystallizes in the rhombohedral space group R 3-C 34, Z = 1, in trigonal setting a = 807.7(2), c = 1339.0(3) pm, V = 756.6(2)-106 pm3, Z = 3. Rh is octahedrally coordinated by three facial S-bonded sulfite groups with R h -S = 222.6(1) pm and three aqua ligands with R h -O bonds R h -O = 217.5(3) pm, elongated by a /raos-influence. The average S -O bond length is 148.0(3) pm. All hydrogen atoms have been located. The OH" ion is coordinated exclusively to Li+. The anions are held together by Li+ cations in octahedral environment and by hydrogen bonds o f medium strength. Alternatively, the structure can be considered to be built o f packages o f two oxygen nets and a metal layer, stacked in a sequence similar to that in the CdCl2-structure.

Syntheses, structures, and properties of multidimensional lithium coordination polymers based on aliphatic carboxylic acids.
Three lithium coordination polymers, [Li4(H2O)2(EDTA)] (1), [Li4(H2O)4(BTCA)] (2), and (H2NMe2)2[Li2(H2O)2(BTCA)] (3) (H4EDTA = ethylenediaminetetraacetic acid, H4BTCA = 1,2,3,4-butane tetracarboxylic acid, H2NMe2 = dimethyl amine), have been synthesized by reacting lithium salts with aliphatic carboxylic acids using a solvothermal method. The structures of all the three complexes have been det...

The crystal structure of the title compound, [Rh(C(6)H(19)N(4))Cl(3)]Cl·0.5H(2)O, is isotypic with the previously reported Ru analogue. The structure contains two crystallographically independent [Rh(Htren)Cl(3)](+) cations with a facial tridentate coordination of the monoprotonated tren ligand [tren = tris-(2-amino-eth-yl)amine], leading to an overall distorted octahedral coordination environm...
