The title compound, [Ni(C12H8N2)3]2[Ag(CN)2]3(NO3)·4.2H2O, crystallizes with two independent [Ni(phen)3]2+ cations (phen is 1,10-phenanthroline; both Ni atoms have threefold symmetry and N6 donor sets), three near-linear [Ag(CN)2]− anions, one nitrate anion (N 3) and 4.2 water molecules of crystallization, some of which are disordered. The [Ag(CN)2]− anions are situated within cavities created by the phenanthroline ligands of adjacent [Ni(phen)3]2+ cations. Some short C—H⋯O and C—H⋯N interactions may help to establish the packing.

An aqueous mixture of Ni(NO3)2.6H2O, 1,10-phenanthroline (phen) and K[Ag(CN)2], was made up in a molar ratio of 1:1:2. After stirring the mixture for 25–30 min, a pink precipitate appeared. This was filtered off and the colourless filtrate left to evaporate slowly at room temperature. After a few days pink blocks of (I) were obtained, which were washed with methanol.
The aromatic H-atoms were included in calculated positions and treated as riding atoms: C—H = 0.95 Å with Uiso(H) = 1.2Ueq(C). The H atoms of the water molecules could not be located.

Geometry. Bond distances, angles etc. have been calculated using the rounded fractional coordinates. All su's are estimated from the variances of the (full) variance-covariance matrix. The cell e.s.d.'s are taken into account in the estimation of distances, angles and torsion angles |
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. |

Supramolecular structures based on [Ag(CN)2]- anions are of significant interest because of their potential for structural, magnetic and catalytic applications, as witnessed by some recent work in this area (Ahmad et al., 2007; Ren et al., 2005; Shorrock et al., 2002; Zhang et al., 2006). We have begun investigations of the structural and chemical properties of metal(II)—Ag(I) coordination polymers that contain the [Ag(CN)2]- anion as a bridging unit (Ahmad et al., 2007). Mixed-ligand metal complexes of 1,10-phenanthroline (phen), and its substituted derivatives, are also interesting because they play an important role in biological systems, such as binding small molecules to DNA (Sastri et al., 2003). A search of the Cambridge Structural Database (CSD V5.29, last update Jan 2008; Allen, 2002) revealed the presence of more than 50 complexes involving the [Ni(phen)3]2+ cation. In the present study we attempted to prepare a coordination polymer consisting of [Ni(phen)2]2+ cations and [Ag(CN)2]-, but instead, the title compound, (I), was isolated.
The molecular structure of (I) is shown in Fig. 1. The two independent [Ni(phen)3]2+ cations have 3-fold symmetry and both Ni atoms have octahedral environments formed by six nitrogen atoms from three 1,10-phenanthroline ligands (Table 1) with normal bond distances and angles. The coordination environment of metal in the [Ag(CN)2]- anion is close to linear [C—Ag—C = 176.78 (13)°].
In the crystal structure of (I), the [Ag(CN)2]- anions are situated within cavities created by the phenanthroline ligands of two [Ni(phen)3]2+ cations (see Fig. 2), hence the silver atoms are isolated from one another. The cationic and anionic units are associated with each other through C—H···O and C—H···N weak interactions (Table 2). The disordered water molecules of crystallization in (I) occupy regions in the vicinity of the 3 symmetry positions (Fig. 3).
The crystal structure of (I) is very similar to that of bis[tris(bipyridine)nickel(II)] tris[dicyanoargentate(I)] chloride nonahydrate, (II), (Černák et al., 1994). Both crystallize in the trigonal space group R3, with a similar disposition in the crystal of the [Ni(phen)3]2+ and [Ag(CN)2]- ionic moeties. In (II), however, the secondary anion, Cl-, is partially distributed over the positions of the water molecules of crystallization (Fig. 4).
