An approximate structure was then dotennined on basis of steric considerations and the Patterson functions P (u, 1/2, Wp), P (u,1/2, w8), P(1/2, v, 1/2-wp), P (1/2, v,1/2-w8), P(u,1/2,O) and P(1/2, v,1/2), where wp and w8 are the intramolecular distances respectively of the two P atoms and the two S atoms related by a mirror plane of the molecule. The structure was confirmed by the Fourier projection p (x, y) and by calculation of structure factors for reflections 00l and hk0.In crystal, the P4S3 molecules are of Hassel-Pettersen type. The present work confirms this conclusion in a convincing fashion. The approximate values of bond lengths and bond angle are P-P = 2.25A, P-S = 2.06A, P-S-P = 103?

The crystal structure of sodium tetraselenite has a monoclinic unit cell with a=5.90A, b=4.82A, c=10.19A, β = 91°20', which contains 2 {NaH3(SeO2)2}. The space group is Gs2-Pn.The equatorial Weissenberg photograph h0l indicates that the projection of the structure onto the plane (010) has a pseudo plane group p6m and a pseudo unit cell with a' = 5.94A, b'=5.90A, r' = 119°50'. The pseudo plane group helped to fix the selenium and sodium atoms in the projection (Figure 1) and the Patterson projectionP(v, w) gave the values of their y coordinates. Then, the selenium and sodium atomswere seen to be distributed according to the space group C2h5 - P21/m. The oxygenatoms were located by a modified Fourier method. The Fourier projections p(x,z) and p(y, 2) (Figure 2 and 3) confirm the structure (Table 2 and Figure 4) satisfactorily.The pyramidal molecule SeO(OH)2 and ion [SeO2(OH)]- in the crystal correspond to the symmetrical structure formulaerespectively, where Se-OH = 1.75-1.82A and Se = O = 1.66-1.69A (Figure 5). The molecules SeO(OH)2 and ions [SeO2(OH)]- are linked through the hydrogen bonds O-H…O = 2.46-2.83A to form infinite chains of composition H3(SeO3)2 (Figure 6) and these chains are held together laterally by the sodium ions between them. The sodium ions are coordinated octahedrally by oxygen atoms (Figure 7).

An X-ray examination of the reddish-brown coloured rhombohedral crystals of the tris-thiourea complex of molybdenum(Ⅲ) chloride MoCl3tu3 (tu=CS(NH2)2) gives the following crystallographic duta: a=8 .78A. c=17.56A, containing 3 MoCl3tu3 per unit cell (pobs=1.83 g/cm3. Pcnlc=1 .73 g/cm3), and belonging to the space group C34-R3. On the basis of the Patterson projection P0 (u. w) we have been able to determine the structure of this non-centro--symmetrical crystal with R=18% for the (hol) diffraction data In this crystal each Mo atom is octahedrally linked with 3 Cl ions and 3 thiourea S atomt. arranged in the cis manner so as to meet the 3-jold requirement of the crystallographic symmetry. The relevant bond lengths and bond angles are as follows: Mo-Cl 2.40A Mo-S 2,44A.

我们应用单晶X射线衍射方法研究了Mo(tu)3Cl3的晶体结构。晶体的空间群为C34-R3;单胞参数力:a=8.78A,C=17.56A。晶体的密度用排量法测得为 1.83g/cm3,单胞内含有三个Mo(tu)3Cl3(密度计算值为1.83g/cm3)。结构的测定主要是通过Patterson投影和电子密度投影的计算来解决的。研究结构表明,在Mo(tu)3Cl3分子中,MO原子和三个Cl原子、三个硫脲的S原子直接配位,这六个原子按顺式排布在八面体的顶点上,因此分子具有三次轴的对称性,而整个晶体是由一层一层的分子所构成的。
