The structure of the title compound, poly[triaquatetra-μ-cyanido-tetracyanidobis(1,4,10,13-tetraoxa-7,16-diazacyclooctadecane)dibarium(II)tetragold(I)], [Au4Ba2(CN)8(C12H26N2O4)2(H2O)3]n, displays O—H⋯N hydrogen bonding between water molecules and cyano ligands and an unusual pattern of aurophilic interactions that yields a monomer, dimer, and trimer of [Au(CN)2]− within the same In two of the five Au positions, the atom resides on a center of inversion. The overall arrangement is that of a coordination polymer assisted by aurophilic and hydrogen-bonded interactions.

A salt of Ba[Au(CN)2]2 was prepared by mixing 162 mg (0.62 mmol) Ba(NO3)2 and 288 mg (1.0 mmol) K[Au(CN)2] in water and heating until both compounds were dissolved. The solution was then put in an ice bath to precipitate out Ba[Au(CN)2]2. An excess of 1,4,10,13-tetraoxa-7,16-diazacyclooctadecane (diaza-18-crown-6), 400 mg (1.5 mmol) was dissolved in methanol and added to the precipitated material. This solution was placed in a 5 mm diameter glass tube and layered with water. After 24 h, suitable prismatic crystals formed.
Hydrogen atoms on water and aza-N atoms were located in a difference map and subsequently refined with Uiso = 1.2Ueq(N or O) and distance restraints of 0.84 (1) Å for O—H, 0.88 Å for N—H and H···H of 1.32 (3) Å for water. The C—H geometry was determined by a riding model with idealized geometry and a C—H distance of 0.99 Å. The largest difference map peaks are due to a small amount of
in one of the aza crown rings but this was not modeled. The disorder is reflected in somewhat elongated thermal ellipsoids in the cation involving Ba2.Data collection: APEX2 (Bruker, 2007); cell

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. |

Two coordinate gold(I) compounds often associate through aurophilic interactions that span the range of ca 2.9 - 3.6 Å (Pathaneni & Desiraju, 1993; Schmidbaur, 1995; Anderson et al., 2007). In previous work (Olmstead et al., 2005) we reported a coordination polymer of Ba(18-crown-6)[Pt(CN)4].2H2O. The title compound represents an extension of that work to the [Au(CN)2]- anion, using a diaza-18-crown-6 to complex Ba2+. A related coordination polymer with aurophilic association between gold(I) species is the result.
The asymmetric unit of the title compound consists of two Ba(diaza-18-crown-6)2+ cations, four dicyanidoaurate anions, and three molecules of water (Fig. 1). There are five gold positions, two of which, Au2 and Au5, are located on centers of inversion. The monomeric dicyanidoaurate is comprised of Au5, linearly coordinated to two cyanide groups. It functions as a linker anion between two Ba2 complexes via N12 of its cyanide group (Fig. 2). It does not participate in any hydrogen bonding nor aurophilic interactions. The closest dicyanidoaurate is that of Au4, at an Au···Au distance of 4.4501 (2) Å. The Au1 and Au2 atoms are involved in the trimer while Au3 and Au4 form the dimer. Distances and angles are reported in Table 1. As shown in Fig. 2, the polymer is connected through a combination of coordination of the [Au(CN)2]- nitrogen atoms to barium and aurophilic interactions. All of the hydrogen atoms of the three coordinated waters behave as hydrogen bond donors to N3, N4, N6, N7 and N8 of the cyanide groups (see Table 2). Fig. 3 depicts how a portion of the polymeric structure is supported by these hydrogen bonds.
The bariums, Ba1 and Ba2, have coordination numbers of 9 and 10, respectively. Ba1 is six-coordinated by the diaza-18-crown-6, two [Au(CN)2]- anions and one water molecule. It is 0.56 (2) Å out of the N2O4 plane of the crown, giving endo and exo faces. One dicyanidoaurate is coordinated to each face while the water molecule coordinates on the exo face. The coordination environment of Ba2 is different. Ba2, which is 0.71 (2) Å out of the N2O4 plane of the crown, is also coordinated by two dicyanidoaurates, but both are found on the exo face. Two water molecules are coordinated to Ba2, one on each face. Four of the eight independent cyanide groups are coordinated through their cyanide N atom to a barium (N5, N6, N9, N12). Interestingly, even though the dimer and trimer differ in their Au···Au distances, they show similar C-Au-Au-C torsion angles that are intermediate between eclipsed and staggered. The average value of the two smaller angles is 53° for the trimer and 55° for the dimer (see Table 1 for details).
