To 30 ml of THF 2,2'-biphenyldioxy-3,3,5,5-tetrakis(4-hydroxymethylphenoxy)- cyclotriphosphazene (1.622 g, 2 mmol) was added under argon. Then, 1.1 ml of phosphorus tribromide in 10 ml of THF was added dropwise and the mixture was stirred for 5 h. The organic solvent was removed under reduced pressure and the residue was dissolved in CHCl3. The residue washed with aq. K2CO3 and extracted with CHCl3, the organic layer was dried over Na2SO4 and then evaporated under reduced pressure. The remaining residue was purified by silica gel
(CH2Cl2/PE) to provide title compound which was recrystallized from CH2Cl2 and single crystals of (I) were obtained by slow evaporation.All H atoms were placed in calculated positions, with C—H = 0.93 or 0.97 Å, and included in the final cycles of
using a riding model, with Uiso(H) = 1.2Ueq(C). There is a single reflection which is considered to be affected by the beamstop.Data collection: XSCANS (Bruker, 2008); 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. |

Cyclotriphosphazenes are of considerable interest not only because of their wide spectrum of chemical and physical properties, but also their importance in synthetic chemistry (Manners, 1996). Different side-group substituents affect the chemical and physical properties of the ring systems in high polymers based on a phosphazene skeleton. Various cyclotriphosphazenes have been successfully developed for a variety of applications, such as flame retardants (Allcock, 1977), elastomers (Allcock, 2000) and biomaterials (Trollsa & Hedrick, 1998), achieved by varying the nature of the substituent side group. Recently, some polydentate cyclotriphosphazene ligands were reported, which showed good nuclease activity with hydrolytic cleavage ability (Wang, Ye, Zhong et al., 2009; Wang, Ye, Ju et al., 2009). To obtain more insight into the selective recognization and efficient cleavage of DNA by different metal complexes of cyclotriphosphazene, the title compound, C40H32Br4N3O6P3 (I), was synthesized and its crystal structure is reported here.
In the crystal structure of (I) (Fig. 1), the part of cyclotriphosphazene ring adopts a planar conformation with an r.m.s. deviation of 0.0247 Å. There are short intermolecular Br···Br contacts: Br1···Br2ii [3.3352 (12) Å] and Br3···Br4iii [3.5868 (15) Å] [for symmetry codes: (ii) -x - 1/2, y - 1/2, -z + 1/2; (iii) -x + 1/2, y - 1/2, -z + 1/2]. The crystal structure is stabilized by weak intermolecular C—H···O hydrogen bond (Table 1).
