In the title coordination polymer, [Ag(2)(NCS)(2)(C(27)H(26)P(2))(2)](n), two centrosymmetrically related Ag(+) cations are linked by two thio-cyanate anions into binuclear eight-membered macrocycles. The Ag⋯Ag separation within the macrocycle is 5.4400 (6) Å. The distorted tetra-hedral coordination about each metal atom is completed by the P atoms of two bridging 1,3-bis-(diphenyl-phosphan-yl)...

The title compound, [Na2(C6H18NSi2)2(C6H16N2)] n , was found to consist of dimeric [Na(NSiMe3)2] units with crystallographically imposed centrosymmetry based upon four-membered NaNNaN rings. The dimers are bridged by N,N,N',N'-tetra-methyl-ethylenediamine ligands, which act in an unusual extended non-chelating coordination mode. This gives a one-dimensional coordination polymer that extends par...

In the title coordination polymer, [Zn(C(8)H(4)O(4))(C(14)H(14)N(4))](n), the Zn(II) atom is coordinated by two N atoms from two 1,2-bis-(imidazol-1-ylmeth-yl)benzene ligands as well as by the two O atoms from two terephthalate ligands, confering a tetra-hedral coordination geometry. The bridging ligands generate a three-dimensional structure.

In the crystal of the title coordination polymer, [Na(C(8)H(5)N(2)O(6))](n), the Na(I) ion is linked to five nearby anions. Their bonding modes are three monodentate carboxyl-ate O atoms, one O,O'-bidentate carboxyl-ate group and one O,O'-bidentate nitro group. This results in an irregular NaO(7) coordination geometry for the metal ion. This connectivity leads to a layered network propagating i...

In the title coordination polymer, {[Ni(C(8)H(10)O(4))(C(10)H(14)N(4))]·0.25H(2)O}(n), the coordination of the Ni(II) ion is distorted octa-hedral. The 1,1'-(butane-1,4-di-yl)diimidazole ligand and the cyclo-hexane-1,4-dicarboxyl-ate dianion bridge metal centres, forming a two-dimensional (4,4) network. The network is consolidated by O-H⋯O hydrogen bonds between the statistically occupied water...

Metal–polymer coordination strategy replaced covalent crosslinking, and improved the chemical resistance of membranes without sacrificing their molecular sieving performance.

In the title one-dimensional coordination polymer, {[Cd(C(11)H(10)O(6))(H(2)O)(3)]·H(2)O}(n), the 2,2'-(5-methyl-1,3-phenyl-enedi-oxy)diacetate dianions connect Cd(II) ions in a head-to-tail fashion to generate zigzag chains. The coordination geometry of the Cd atom is distorted penta-gonal bipyramidal. There are O-H⋯O hydrogen bonds between the carboxyl O atoms, the aqua ligands and the uncoor...

In the title coordination polymer, {[CdI(2)(C(13)H(11)N(3))]·0.5CH(4)O}(n), each Cd(II) center is four-coordinated by two N-atom donors from two 1-(4-pyridylmeth-yl)-1H-benzimidazole (L) ligands and two iodide anions, forming a tetra-hedral coordination geometry. L ligands bridge adjacent Cd(II) ions, generating two crystallographically independent approximately orthogonal one-dimensional chain...

In the title coordination polymer, [Zn(C(14)H(11)NO(3))(C(2)H(6)OS)](n), each Zn(II) ion is five-coordinated in a slightly distorted trigonal-bipyramidal coordination environment, formed by three O atoms from two 2-[(2-oxido-1-naphth-yl)-methyl-eneamino]propanoate ligands, one O atom from a dimethyl sulfoxide mol-ecule and the N atom from the amino-propanoate ligand. The propanoate ligands brid...

The new porous phosphine coordination material, PCM-11, is an unusual 8,4-connected coordination polymer with an open 3-D pore structure, formed by reaction of Mg(II) with tris(para-carboxylato)triphenylphosphine oxide. The highly ionic nature of the metal-ligand bonding results in excellent thermal stability upon desolvation (>460 °C). PCM-11 is easily activated for small molecule sorption at ...
