چکیده
The title compound, [Tl(2)(C(3)H(10)NO(9)P(3))](n), a Tl(I) organic-inorganic hybrid complex, was synthesized by the reaction of nitrilo-tris(methyl-enephospho-nic acid) with thallium(I) nitrate. There are two types of Tl(+) ions in the complex, with coordination numbers of eight and seven and with stereochemically active and inactive lone-pair electrons, respectively. In the crystal, the doubly deprotonated ligands form two-dimensional hydrogen-bonded layers through O-H⋯O hydrogen bonds. The NH group is involved in a trifurcated intra-molecular hydrogen bond. Coordination of the phospho-nate ligands to the Tl(+) ions creates a three-dimensional structure.

The title compound, {(C(2)H(10)N(2))[Tl(2)(C(10)H(2)O(8))(H(2)O)(2))]}(n), was prepared using (enH(2))(2)(btc)·2H(2)O and thallium(I) nitrate (en = ethyl-enediamine and btcH(4) = benzene-1,2,4,5-tetra-carboxylic acid). The enH(2) cation and btc ligand are each located on an inversion centre. The Tl(I) atom is seven-coordinated by three btc ligands and two water mol-ecules in an irregular geomet...

In the polymeric title compound, [Zn(C(7)H(9)NO(7)P(2))](n), the zinc(II) centre displays a tetra-hedral coordination geometry provided by four O atoms from three different phospho-nate groups. The crystal structure consists of ladder chains parallel to the b axis built up from vertex-sharing of ZnO(4) and PO(3)C tetra-hedra. The chains are linked by strong intra- and inter-chain O-H⋯O and N-H⋯...

The asymmetric unit of the title compound, [Na(2)(C(8)H(8)O(8))](n), contains one Na(+) ion and half of a 2,3-bis(carboxymethyl)butanedioate (H(2)BTC(2-)) dianion, which lies on a center of symmetry. The dianion exhibits a μ(10)-bridging mode. Each Na atom lies in a NaO(6) octa-hedron defined by six O atoms from five dianions. Adjacent NaO(6) octa-hedra share a common O-O edge, generating a bio...

The structure of Tl(2)Mo(9)Se(11), dithallium nona-molybdenum undeca-selenide, is isotypic with Tl(2)Mo(9)S(11) [Potel et al. (1980 ▶). Acta Cryst. B36, 1319-1322]. The structural set-up is characterized by a mixture of Mo(6)Se(i) (8)Se(a) (6) and Mo(12)Se(i) (14)Se(a) (6) cluster units in a 1:1 ratio. Both components are inter-connected through inter-unit Mo-Se bonds. The cluster units are cen...
