The title compound, {[Tm(C(7)H(3)NO(4))(C(7)H(4)NO(4))(H(2)O)(2)]·2H(2)O}(n), is isotypic with the analogous Tb(III) compound [Li et al. (2009 ▶). Acta Cryst. E65, m410]. All interatomic distances and angles and the hydrogen-bond geometries are very similar for the two structures. The refined Flack parameter of 0.49 (2) suggests inversion twinning.

Reacting trimesic acid (HTMA, CHO) with CaCl and MCl at 110 °C under hydrothermal conditions gave the isostructural heterobimetallic coordination polymers (CPs) catena-poly[[tetraaquazinc(II)]-μ-5-carboxybenzene-1,3-dicarboxylato-[tetraaquacalcium(II)]-μ-5-carboxybenzene-1,3-dicarboxylato], [CaZn(HTMA)(HO)], 1, and catena-poly[[tetraaquacobalt(II)]-μ-5-carboxybenzene-1,3-dicarboxylato-[tetraaquacalcium(II)]-μ-5-carboxybenzene-1,3-dicarboxylato], [CaCo(HTMA)(HO)], 2. Compounds 1 and 2 crystallize in the monoclinic space group C2/c. The solid-state structures consist of eight-coordinate Ca ions and six-coordinate M ions.

In the polymeric title compound, {[Na(CHNOS)(HO)]·2HO} , sixfold coordinated Na cations are linked into a chain parallel to [010] by sharing common water mol-ecules. Next to the four bridging water mol-ecules, each Na cation of the chain is bonded to the O atom of a terminal water mol-ecule and an O atom of the SO group of the sulfonate anion. Classical O-H⋯O, O-H⋯N and N-H⋯O hydrogen bonds and additional π-π inter-actions connect these chains into a three-dimensional network.

Single crystals of three novel transition-metal oxalates, dirubidium di-aqua-dioxalatocobalt(II) dihydrate or dirubidium cobalt(II) bis-(oxalate) tetra-hydrate, Rb[Co(CO)(HO)]·2HO, (I), -poly[dirubidium [[di-chlorido-cobalt(II)]-μ-oxalato]] or dirubidium cobalt(II) dichloride oxalate, {Rb[CoCl(CO)]} , (II), and poly[dipotassium [tri-μ-oxalato-copper(II)dilithium] dihydrate] or dipotassium dilithium copper(II) tris-(oxalate) dihydrate, {K[LiCu(CO)]·2HO} , (III), have been grown under hydro-thermal conditions and their crystal structures determined using single-crystal X-ray diffraction. The structure of (I) exhibits isolated octa-hedral [Co(CO)(HO)] units, whereas (II) consists of chains of Co ions bridged by bidentate oxalato ligands and (III) displays a novel tri-periodic network of Li and Cu ions linked by oxalato bridging ligands.

The title one-dimensional copper(II) coordination polymer, {[Cu(SO)(CHN)]·CHNO·HO} or {[Cu(bzi)(μ-OSO)]·HO·DMF} (bzi = 1-benz-yl-imidazole, CHN; DMF = ,-di-methyl-formamide, CHNO), is constructed by monodentate bzi ligands and bridging sulfate anions, leading to chains propagating parallel to the axis. Within a chain, there are two crystallographic independent Cu ions, each with site symmetry , which form [CuNO] and [CuNO] polyhedra alternating along the chain direction. The crystal structure is consolidated by weak hydrogen-bonding, C-H⋯π and π-π inter-actions, leading to the formation of a three-dimensional supra-molecular network.

The asymmetric unit of the title compound, -poly[[[(1,4,8,11-tetra-aza-cyclo-tetra-decane-κ , , , )nickel(II)]-μ-cyanido-κ :-[bis-(cyanido-κ)nickel(II)]-μ-cyanido-κ :] dihydrate], {[Ni(CN)(CHN)]·2HO] or [{[Ni(CHN)][Ni(CN)]}·2HO] , consists of a pair of crystallographically non-equivalent macrocyclic cations and anions. The nickel(II) ions (all with site symmetry ) are coordinated by the four secondary N atoms of the macrocyclic ligands, which adopt the most energetically stable -III conformation, and the mutually N atoms of the tetra-cyano-nickelate anion in a slightly tetra-gonally distorted NiN octa-hedral coordination geometry. The [Ni(CN))] anion exhibits a bridging function, resulting in the formation of parallel polymeric chains running along the [10] direction.
