Structure of organic and organoelemental compounds

The structure of eight organic and organoelemental compounds was determined by X-ray structural analysis (XRD). XRD analysis of compounds was performed on an automatic four-circle diffractometer D8 Quest Bruker (Мо Кα , λ = 0,71073 Å, 293 К. 1 (C23H30Cl4O2PRuS2, P -1, a = 8. 4181(3), b = 8.9389(3), c = 11.1396(4) Å, a = 69.754(1), β = 81.913(2), g = 64.491(1) deg., V = 709.75(4) Å3, Z = 1. 2 (C21H18Cl4NP, P 21/n, a = 9.846(6) Å, b = 15.782(14) Å, c = 15.111(10) Å, a = 90 , β = 91.027(18) , g = 90 deg., V = 2348(3) Å3, Z = 4. 3 (C30H24NO3Sb, P -1, a = 11.101(6), b = 12.684(6), c = 19.359(9) Å, a = 80.973(17), β = 80.17(2) , g = 72.31(3) deg., V = 2543(2) Å3, Z = 4. 4 (C21H15Br3Sb, P -1, a = 6.273(12), b = 12.83(2), c = 13.26(3) Å, a = 78.67(8), β = 84.33(9) , g = 80.81(7) deg., V = 1031(3) Å3, Z = 2. 5 (C24H22BrOP, P -1, a = 10.025(10), b = 10.676(10), c = 10.706(13) Å, a = 77.56(4), β = 71.80(4) , g = 83.26(3) deg., V = 1061(2) Å3, Z = 2. 6 (C21H21O3Sb, R -3, a = 13.27(3), b = 13.27(3), c = 19.24(7) Å, a = 77.56(4), β = 90 , g = 120 deg., V = 2935(20) Å3, Z = 6. 7 (C26H21ClNP, P 21/n, a = 9.456(6), b = 14.733(9), c = 16.271(9) Å, a = 90, β = 104.83(2), g = 90 deg., V = 2191(2) Å3, Z = 4. 8 (C19H18ClOP, P 21/c, a = 8.888(9), b = 17.795(19), c = 11.278(12) Å, a = 90, β = 99.52(4) , g = 90 deg., V = 1759(3) Å3, Z = 4.
