Tris(propane-1,2-diamine-κ2N,N′)nickel(II) tetra­cyanidoplatinate(II)

I. Potočňák, M. Vavra, D. Steinborn and C. Wagner
In the title compound, [Ni(C3H10N2)3][Pt(CN)4], the [Pt(CN)4]2− anion with the environment of the PtII atom, lying on a mirror plane, is square planar, whereas the NiII atom in the [Ni(C3N2H10)3]2+ cation, also lying on a mirror plane, has a slightly distorted octa­hedral coordination geometry. Three chiral 1,2-diamino­propane mol­ecules, which are disordered equally over two sets of positions, adopt Δ(δδδ) and Δ(λλλ) configurations. The average Ni—N and Pt—C bond lengths are 2.131 (10) and 1.988 (10) Å, respectively. The cations and anions are connected by N—H...N hydrogen bonds.

Comment top

The title compound, [Ni(pn)3][Pt(CN)4] (pn = 1,2-diaminopropane) has been prepared by a chance within our studies on the role of hydrogen bonds as possible exchange paths for magnetic interactions in low-dimensional compounds. The compound consists of discrete [Ni(pn)3]2+ cations and [Pt(CN)4]2- anions (Fig. 1). Selected bond lengths and angles are given in Table 1. The NiII atom is coordinated by six N atoms of three racemic pn ligands, which are disordered over two sets of positions, with site occupancies of 0.50 (except methylene and methine C atoms), thus forming Δ(δδδ) and Δ(λλλ) configurations. Moreover, a mirror plane passes through the tetracyanoplatinate anion (N1, C1, Pt, C2 and N2 atoms) and the [Ni(pn)3]2+ cation (Ni, C31 and C41 atoms). The coordination geometry around the NiII atom can be described as octahedral. The two N atoms occupying axial positions form an angle of 170.6 (4)° and the Ni—N bond distances range from 2.118 (9)–2.142 (10)Å [mean bond length is 2.131 (10) Å], in good agreement with the values reported of other [Ni(pn)3]2+ complexes (Behrens et al., 2003; Kuchár & Černák, 2008; Saha et al., 2005). Octahedral coordination geometry around the Ni atom was observed also in other compounds with [Ni(pn)3]2+ cation (Nasanen et al., 1964; Lin et al., 2005). The square-planar geometry of [Pt(CN)4]2- is in good agreement with those of the previous studies with average Pt—C bond lengths of 1.988 (10) Å. The structure is stabilized also by the N—H···N hydrogen bonds between the cations and anions (Table 2).

Experimental top

The title compound were prepared by a chance during our attempts to prepare chain-like [Ni(pn)2][Pt(CN)4] compound suitable for magnetic studies. A mixture of a 10 ml aqueous solution of NiSO4.6H2O (0.132 g, 0.5 mmol) and pn (0.086 ml, 1.0 mmol) was stirred for 30 min and a 10 ml aqueous solution of K2[Pt(CN)4].3H2O (0.216 g, 0.5 mmol) was added. The pink precipitate thus formed was dissolved by addition of a concentrated solution of ammonia (20 ml). After few days, pink crystals of the title compound were filtered off and dried in air.

Refinement top

H atoms were positioned geometrically and refined as riding atoms, with N—H = 0.90 Å, C—H = 0.97Å (CH2), 0.98Å (CH) and Uiso(H) = 1.2Ueq(C,N) and with C—H = 0.96Å (CH3) and Uiso(H) = 1.5Ueq(C). The highest residual electron density and the deepest hole were found 1.01 and 0.88 Å from the Pt atom, respectively.
