“…During the etching process, the peak of B1s and Zn2p3/2 do not show obvious energy displacement, while P2p peak slightly shifts to right and then left. According to the prior reports, P can form compounds with Zn and S, including ZnP 2 , Zn 3 P 2 , P 4 S 10 , P 4 S 7 , P 4 S 5 and P 4 S 3 [15,16], and the corresponding P2p binding energy levels are 129.8 eV, 129.8 eV, 134.0 eV, 132.7 eV, 132.0 eV and 130.5 eV, respectively. Unfortunately, these positions do not appear in profile of our results.…”

“…He gave the diamond (or zinc blende) and cristobalite structures as examples, and he further indicated that the 'super-tetrahedral' groups can be considered as basic 'topological' units in the formation of more complicated structures. Some more examples of the cage structures are the tetrahedral groups P4O10 (Cruickshank, 1964), P4S10 (Vos, Olthof, van Bolhuis and Botterweg, 1965), and S^Sfo" (Chao, 1971;Prince, 1971;and Colville and Anderson, 1971). …”

The crystal structure of ZnBr 2 is tetragonal, space group 14^/acd, a = 11.389(4), c = 21.773(9) Â, K=2826(3) Α 3 ·, μ=308.2 cm -1 . Dm=4.208, Ζ=32, Z)x=4.233 Mg m -3 . The structure was determined from 146 independent observed [F> 2a(F)] reflections to an R value of 0.074. The bromide ions are arranged in an fee array with Zn atoms filling in 1/4 of the tetrahedral sites. This results in the formation of 'super-tetrahedraF groups of Zn 4 Br 6 Br 4/2 , which again interconnect to give a three-dimensional network. These groups are similar to those of P 4 O 10 , hexamethylenetetramine, [N 4 (CH 2 ) 6 ], and the large 'cage', Zn 4 S 6/2 S 4/4 , present in the zinc blende structure. However, the cage groups in ZnBr 2 have point group 3 in this space group and they are only slightly deviated from 33m, the point group for idealized cages. The mean Zn -Br distance is 2.42(1 ) Â, and the mean Br-Zn -Br angle is 109(3)°. All the Br atoms are 2-coordinated, withZn-Br-Zn angles ranging from a mean value of 105.3(3) for intracage bonds to 107.9(5)° for intercage connections. The ZnBr 2 structure is related to those of Hgl 2 , Be 3 P 2 and Cd 3 As 2 in a very interesting way.

“…A difference of this order can therefore be attributed to the different coordination of the phosphorus atom, leaving the cross-ring repulsions to account for only some 0.03 A, the difference between the bond length in the di-and higher phosphazanes. The mean P=S bond length (1.928 A) does not differ greatly from those found in the cyclodiphosphazanes [NMeP(S)CI]2 and trans-[NPhP(S)Ph]2 or from the terminal P=S bonds in P4S5, P4Sv and P4S10 (Vos, Olthof, van Bolhuis & Botterweg, 1965). It is however, significantly shorter than the P=S bonds in diphosphine disulphides, e.g.…”

Crystals of Ph]2 are triclinic, a= 8"06, b=9"34, c= 13.13 A, ~=93"6, t= 104.2, y=99.2 °, space group P], 2 molecules in the unit cell. The atomic positions have been determined by least-squares refinement from X-ray diffractometer intensity data, the final R being 0.095 for 3101 reflexions. The two molecules in the unit cell lie on centres a.J of symmetry at (0,0,0) and (2, z-,½) and in consequence the phosphazane ring is planar. These molecules, although not mutually related by symmetry, differ in shape only by the position of the terminal carbon atom of the ethyl group. Mean bond lengths and angles are: P-N 1.688, P-S 1.928, P-C 1-807, N-C 1.47 ~, N-P-N 83.25 °, and P-N-P 96.75 °. The geometry of the molecule is discussed in terms of steric factors.
