 Title    Synthesis, IR and X-Ray Studies of a Dioxouranium(VI) Nitrate Complex with N,N'-Tetraethyl-NM -trichloracetylphosphortriamide  
 Abstract    A new dioxouranium(VI) nitrate complex with N,N'-tetraethyl-N"-trichloracetylphosphor-triamide (HL = CCl3C(0)N(H)P(0)(NEt2)2) of composition U0 2 (HL)2(N0 3)2 (1) has been synthesised. The IR spectroscopic data reveal that the ambidentate ligand is coordinated to the metal center in a monodentate manner via the phosphoryl oxygen atom. The crystal and molecular structure of 1 has been determined from X-ray diffraction data (triclinic, space group Pi with a = 9.225(2), b = 10.360(2), c = 12.249(2) A, a = 100.02 (1),/3 = 103.81(1), 7 = 108.80 (1)°, Z = 1; R = 0.037 for 4092 unique reflections. The structure is made up of centrosymmetric molecules in which the neutral ligands HL are monocoordinated. Phosphoryl and carbonyl groups of the HL moieties are in the trans positions to each other. The axial vertices of the distorted hexagonal bipyramid of uranium are occupied by two oxo ligands [U-0 1.753(5) A] while six oxygen atoms of phosphoryl and nitrate groups lie in the equatorial plane [U-0 2.347(5)-2.547(6)A],

 Title    Carbacylamidophosphates: Synthesis, Properties, and Structure of Dimorfolido-N-trichloroacetylphosphorylamide  
 Abstract    Dimorpholido-N-trichloroacetylphosphorylamide: CCl3C(0)NHP(0)[N(CH2CH2)2 0 ] 2 [HL] and its sodium [NaL] and morpholine [HN(CH2CH2) 2 0 HL] salts were synthesized for the first time. The compounds were studied by IR spectroscopy and assignments of the characteristic IR bands have been made. The structure of [HL] was determined by X-ray diffraction. Crystals are monoclinic, a = 11.412(2) A, b = 16.056(3) A, c = 9.622(2) Ä, ß = 108.55(3)°, space group P2i/c; Z = 4. The refinement of the structure converged at R = 0.066. The molecules are connected into centrosymmetric dimers via hydrogen bonds formed by the phosphorylic oxygen atoms and hydrogen atoms of amide groups.

 Title    Synthesis, IR and X-Ray Studies of Tetra(N,N'-tetraethyl-N"-benzoyl- phosphorictriamide)-tetra(/x-3-methoxo)-tetra(methanol)tetra-NickeI(II)  
 Abstract    A new nickel(II) complex with N,N'-tetraethyl-N"-benzoylphosphortriamide (HL = C6H5C(0)N(H)P(0)(NEt2)2) of composition Ni4L4(OCH3)4-(HOCH;04 (1) has been synthe­ sized. The crystal and molecular structure of 1 has been determined from the X-Ray diffraction data (tetragonal, space group P42)C with a = 17.000(2) A, c = 15.338(3) A, Z = 2; R = 0.0399 for 1412 unique reflections). The structure is made up of cubane-like tetramers. In the corners of a cube there are 4 atoms of nickel and 4 atoms of oxygen of methoxy groups. The nickel atoms are characterized by a slightly distorted octahedral environment, which consists of three oxygen atoms of methoxy groups, carbonylic and phosphorylic oxygen atoms of the ligand L~, and an oxygen atom of a methanol molecule. The ligands L~ coordinate to the metal ion forming a chelate via the oxygen atoms of carbonylic and phosphorylic groups.

 Title    Structure of Tl(18-cr0wn-6){Cl3C C (0)N P (0)(0C H 3)2}: Coordination of the Ionic Multidentate Weakens the Interaction of the Metal Atom with the Crown Ether  
 Abstract    The thallium(I) dimethyl-N-trichloroacetylamidophosphate complex with a 18-crown-6 of the composition Tl(18-crown-6){L} (L = {Cl3CC(0)NP(0)(0 CH3)2}_) has been prepared and characterized by means of IR spectroscopy and X-ray diffraction (orthorhombic, space group P2,2,2, with a = 8.660(1), b = 11.557(2), c =26.296(3) A, Z = 4, V = 2631.8(6) Ä3; R\ = 0.0285 and wR2 = 0.0558 for 4314 unique reflections). It was shown that (L~) is coordinatedoto the central atom in a bidentate manner via oxygen atoms of phosphoryl [Tl-O(l) 2.678(4) A] and carbonyl groups [Tl-0(2) 3.012(6) A], The Tl(18-crown-6)+ moiety adopts a typical "sunrise" coordination with the metal atom laying 1.134(2) A above the mean plane of the oxygen atoms of the macrocycle. This deviation is the highest value of the structurally examined Tl(18-crown-6)+ complexes. The Tl-O (etheric) separations are in the range 2.913(4) -3.198(5) A (av. 3.030(6) A).

 Title    Carbacylamidophosphates: Structure and Properties of Bis(N,N,-morpholido)-[(N"-morpholido)-carboxamido] phosphate  
 Abstract    The bis(N,N'-morpholido)-[(N"-morpholido)-carboxamido] phosphate: 0 (CH2 CH2)NC(0)-N(H)P(0)[N (CH 2 CH 2)0 ] 2 [HL], has been prepared and characterized by means of IR, 31P and 'H NM R spectroscopy and X-ray diffraction (triclinic, a = 9.282(2), b = 9.308(2), c = 21.341(4) Ä, a = 80.79(3)°, ß = 80.92(3)° 7 = 66.92(3)°, V = 1665.1(6) Ä 3, space group P i, Z = 4 and R = 0.0423, wR2 = 0.1303 for 6774 unique reflections used). The unit cell consists of two independent molecules connected by hydrogen bonds N-H...O=P into non-symmetric dimers. The compound behaves as a HL molecule with a protonation constant corresponding to the -C (0)N (H)P (0)-group of pK = 8.65 as determined by potentiometric studies.
