The title compound, {[Ni(SO4)(C6H16N2)(H2O)2]·H2O}n, contains a NiII atom that is coordinated nearly octa­hedrally by a chelating tetra­ethyl­enediamine (tmeda) ligand, two water mol­ecules in a cis arrangement and two O atoms of two sulfate anions in a trans arrangement. The sulfate anions act as μ2-bridging ligands leading to a chain structure of alternating NiO4N2 octa­hedra and SO4 tetra­hedra parallel to [001]. The polymeric chains are linked by O—H⋯O hydrogen bonds between coordinating water mol­ecules and sulfate anions to give double strands. There is a lattice water mol­ecule which is also involved in O—H⋯O hydrogen bonding between adjacent [Ni(SO4)(tmeda)(H2O)2] chains.

Comment top

The title compound, {[Ni(H2O)2(C6H16N2)(SO4)].H2O}n, (I), forms a coordination polymer which consists of an alternating arrangement of [Ni(H2O)2(tmeda)]2+ (tmeda is tetraethylenediamine) cations and SO42- anions. The coordination around nickel(II) is roughly octahedral with a chelating tmeda ligand, two water molecules in cis positions and two oxygen atoms of the SO42- anions in a trans arrangement (Fig. 1). In a polyhedral description the chain consists of corner sharing NiN2O4 octahedra and SO4 tetrahedra (Fig. 2). The observed Ni—N (2.141 (2), 2.1453 (19) Å) and Ni—O(aqua) distances (2.0639 (17), 2.084 (2) Å) agree well with the values reported for other nickel(II) complexes containing tmeda and aqua ligands, e.g. [Ni6(CO3)4(tmeda)6]Cl4.CH2Cl2 (Anderson et al., 2009) and [Ni(C4O4)(tmeda)(H2O)2].H2O (Erer et al., 2010). A related chain structure consisting of corner-sharing NiO4(H2O)2 octahedra and SO4 tetrahedra has been observed in the compound [C2N2H10][Ni(SO4)2(H2O)2] (Behera & Rao, 2006). However, in contrast to compound (I) each NiO4(H2O)2 octahedron of the chain is connected to four SO4 tetrahedra.

The crystal packing of the [Ni(H2O)2(tmeda)]SO4 chains is supported by a network of hydrogen bridges (Figs. 2 and 3). Each of the water molecules attached to nickel forms an intrachain hydrogen bond of the type R11(6) or R11(6) to a sulfate oxygen atom. The lattice water molecule, which acts as a linker between the chains, forms two hydrogen bonds of the type R11(2) to sulfate oxygen atoms and a D11(2) hydrogen bond to a coordinating water molecule. Additonally, there are hydrogen bond motifs of the type R22(12) which are formed between coordinating water molecules and sulfate oxygen atoms of neighbouring chains. As a result of these interchain hydrogen bridges, double strands are formed which propagate parallel to [001]. The arrangement of the double strands corresponds to a distorted hexagonal rod packing.

Experimental top

3.7 ml (46 mmol) of pyridine were added to a solution of 2.0 g (7.6 mmol) of nickel sulfate hexahydrate in 50 ml of water. 1.2 ml (8.0 mmol) of tmeda were added and all volatile compounds removed under reduced pressure at 333 K. The resulting solid was recrystallized from water and washed with ether to obtain the title compound in a yield of 85% (2.1 g).

Refinement top

The hydrogen atoms of the tmeda ligand were positioned geometrically and were refined using a riding model with U(H) = 1.2 Ueq(C). Hydrogen atoms of the water molecules were located from difference Fourier maps and were refined with O—H distances fixed in the range of 0.83–0.84 Å and U(H) = 1.2Ueq(O).

Special details top

Geometry. All e.s.d.'s (except the e.s.d. in the dihedral angle between two l.s. planes) are estimated using the full covariance matrix. The cell e.s.d.'s are taken into account individually in the estimation of e.s.d.'s in distances, angles and torsion angles; correlations between e.s.d.'s in cell parameters are only used when they are defined by crystal symmetry. An approximate (isotropic) treatment of cell e.s.d.'s is used for estimating e.s.d.'s involving l.s. planes.

Refinement. Refinement of F2 against ALL reflections. The weighted R-factor wR and goodness of fit S are based on F2, conventional R-factors R are based on F, with F set to zero for negative F2. The threshold expression of F2 > σ(F2) is used only for calculating R-factors(gt) etc. and is not relevant to the choice of reflections for refinement. R-factors based on F2 are statistically about twice as large as those based on F, and R- factors based on ALL data will be even larger.
