Poly[diammonium [(μ4-butane-1,2,3,4-tetra­carboxyl­ato)zincate] tetra­hydrate]

In the title compound, {(NH(4))(2)[Zn(C(8)H(6)O(8))]·4H(2)O}(n), the asymmetric unit contains one ammonium cation, half of a butane-1,2,3,4-tetra-carboxyl-ate anion, one Zn(2+) cation and two water mol-ecules. The butane-1,2,3,4-tetra-carboxyl-ate ligand is located about an inversion centre at the mid-point of the central C-C bond. The Zn(2+) cation is situated on a twofold rotation axis and is...

Poly[bis­[chlorido­cop­per(I)]-μ4-1,4-bis­[1-(3-pyridylmeth­yl)-1H-benzimid­azol-2-yl]butane]

The title Cu(I) coordination polymer, [Cu(2)Cl(2)(C(30)H(28)N(6))](n), was obtained by reaction of CuCl(2)·2H(2)O and 1,4-bis-[1-(3-pyridyl-meth-yl)-1H-benzimidazol-2-yl]butane. Each Cu(I) cation is three-coordinated by a ClN(2) donor set. The anion acts as a tetra-dentate ligand, linking Cu(I) centres into a polymeric chain.

Poly[[{μ4-2,2′-[butane-1,4-diylbis(sulfanedi­yl)]bis­(1,3,4-thia­diazole)}silver(I)] perchlorate sesquihydrate]

In the polymeric title compound, {[Ag(C(8)H(10)N(4)S(4))]ClO(4)·1.5H(2)O}(n), the Ag(I) atom has a slightly distorted trigonal-planar coordination geometry provided by three N-atom donors from the thia-diazole rings of three symmetry-related 2,2'-[butane-1,4-diylbis(sulfanedi-yl)]bis-(1,3,4-thia-diazole) ligands. Centrosymmetrically related Ag(I) atoms are bridged by the N-N fragments of rings,...

Poly[(μ4-biphenyl-3,3′-dicarboxyl­ato)bis[μ2-1,1′-(butane-1,4-di­yl)diimidazole](μ2-oxalato)dimanganese(II)]

In the title coordination compound, [Mn(2)(C(14)H(8)O(4))(C(2)O(4))(C(10)H(14)N(4))(2)](n), the biphenyl-3,3'-dicarboxyl-ate and oxalate anions, both situated on inversion centres, function in a bridging mode, linking the dinuclear Mn(II) atoms into wave-like layers. Each 1,1'-(1,4-butane-1,4-di-yl)diimidazole ligand coordinates to two Mn(II) atoms located in adjacent layers via Mn-N coordinati...

Poly[μ-aqua-[μ-1,1′-(butane-1,4-di­yl)diimidazole]bis­(μ4-naphthalene-1,4-dicarboxyl­ato)dicadmium(II)]

In the title compound, [Cd(2)(C(12)H(6)O(4))(2)(C(10)H(14)N(4))(H(2)O)](n), the coordination polyhedron around each Cd(II) ion is a distorted CdNO(5) octa-hedron. The water O atom has site symmetry 2 and the complete 1,1'-(butane-1,4-di-yl)diimidazole (L) ligand is generated by inversion. The naphthalene-1,4-dicarboxyl-ate and L ligands bridge the metal centres, forming a three-dimensional fram...
