In the title compound, C24H56N4P2, the distance between the P atoms [2.2988 (8) and 2.3013 (13) Å in the major and minor occupancy components, respectively] is one of the longest reported for uncoordinated diphosphanes. The whole molecule is disordered over two positions with site-occupation factors of 0.6447 (8) and 0.3553 (8). The structure adopts the conformation in the solid state [N—P—P—N torsion angle = 14.7 (5)°].

The work was carried out using the standard vacuum-nitrogen line and Schlenk techniques. Solution of 0.244 g (0.447 mmol) (iPr2N)2P—P(SiMe3)Li . 2.6THF in 2 ml DME was added dropwise into solution of 0.059 g (0.202 mmol) [Cp2ZrCl2] in 2 ml of DME at 233 K. The mixture immediately turned red. The resultant solution was studied using 31P-NMR. Then the volume was reduced to about 2 ml and the concentrate stored for 3 days at 269 K. After this time the solution yielded small colourless crystals of (I).
All H atoms were placed in calculated positions and refined as riding on their carrier atoms with respective Uiso(H) values: C—H = 0.98 Å (CH3) and Uiso(H) = 1.5 Ueq(C), C—H = 1.00 Å (CH) and Uĩso(H) = 1.2 Ueq(C). The whole molecule was refined as disordered over two positions with site occupation factors of 0.6447 (8) / 0.3553 (8). Additionally, P–N bond lengths were restrained to be the same and all N atoms displacement ellipsoids were restrained to be equal to improve numerical stability. This kind of disorder was noted already for the structurally similar {P[N(SiMe3)2](NiPr2)2 (Bezombes et al., 2004).

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. |

In the course of our studies on phosphinophosphinidene ligands R2P–P we have investigated reactions of diphosphanes R2P—P(SiMe3)Li with transition metals chlorides (Pikies et al., 2004). The title compound, (iPr2N)2P–P(NiPr2)2 (I), turned out to be the main product in the reaction of (iPr2N)2P–P(SiMe3)Li with [Cp2ZrCl2] (mol ratio 2:1 in DME); (I) is formed as a result of cleavage of the P–P bond in the starting material, (iPr2N)2P—P(SiMe3)Li. We observed the formation of diphosphanes (R2P–PR2) in every reaction of [Cp2ZrCl2] with R2P—P(SiMe3)Li in different yields. The formation of diphosphane in exceptionally preferred in the case of R=iPr2N. The crystal structure of (I) is presented in this paper.
The whole molecule of the title compound was disordered over two positions with site occupation factors of 0.6447 (8) and 0.3553 (8) referred to as part A and B, respectively; the part A is presented in Fig. 1. The structure adopts the synperiplanar conformation in the solid state (N1—P1—P2—N4 torsion 14.7 (5)°). The most striking structural feature in (I) is P1–P2 bond length (2.2988 (8) Å in part A and 2.3013 (13) Å in part B). This distance between phosphorous atoms is one of the longest reported for uncoordinated diphosphanes. There is only one report of diphoshane {P[CH(SiMe3)2]2}2 with a longer P–P bond of 2.310 (7) Å (Hinchley et al., 2001). Another diphosphane which contains amino grups [N(SiMe3)2](NiPr2)P–P[N(SiMe3)2](NiPr2) has slightly shorter P–P distance of 2.291 (4) Å (Bezombes et al., 2004). These three diphosphanes R2P–PR2 posses R groups which have a form of –AX2, where A = N or CH and X are voluminous rests SiMe3 or iPr. The steric effects of bulky R groups like tBu are not sufficient for such an elongation (Hinchley et al., 2004) and for tBu2P–PtBu2 a P–P distance of 2.235 Å was reported. The presence of four nitrogen substituents in the molecule is not sufficient cause of the elongation either. For DMP(iPr2N)P–P(NiPr2)DMP (DMP = 2,6-dimethylopiperidine) the P–P distance of 2.259 (2) Å was reported (Bender et al., 1994). The enhanced stabilities of related radicals P[CH(SiMe3)2] or P[N(SiMe3)2](NiPr2) can be seen as a possible explanation of the elongation phenomena. These diphosphanes dissociate very easy into relatively stable radicals (Hinchley et al., 2001).
To study repulsions of substituents around P-atom we analysed the average angle around P atoms. Its deviation from orthogonality (90°) can be a rough measure of the steric crowding. The average angle in (I) around P atoms is 105.98°. The widest ones, above 110°, are N—P—P angles for N1 and N4 (in disorder part A), perhaps because nitrogen atoms are in synperiplanar position. The N—P—P angles for N3 and N2 atoms are only 93.5 (6)° and 92.0 (4)°, respectively. For comparison, in the case of very small groups around P-atoms, i.e., for Me2P–PMe2 the average angle is 98.40° (close to orthogonality) (Mundt et al., 1988) and for (F3C)2P–P(CF3)2 is only 96.67° (Becker et al., 1999). For the most crowded diphosphanes, i.e., for tBu2P–PtBu2, this average angle is 109.99° (Hinchley et al., 2004) and for [(Me3Si)2CH]2P–P[CH(SiMe3)2]2 is 105.23° (Hinchley et al., 2001).
