Abstract The title compound has been prepared in high yield from K2[PtCl4] and 1,5-bis(diphenylphosphano) pentane in dry CH2Cl2. The crystals are monoclinic, space group P21/c with lattice parameters a = 11.733(3), b = 17.229(5), c = 13.743(4) Å, and β= 92.37(3)°; Z = 4. An X-ray analysis shows that the complex is monomeric and that it has a planar cis-configuration.

The structure of a tetragonal crystal of the title compound was determined by X-ray diffraction. The space group was found to be P4/nmm with a 6.202(2) and c 7.410(1) � and Z 2. The structure consists of infinite sheets of distorted VO6 octahedra and PO4 tetrahedra linked by shared oxygen atoms. Shared water molecules link these sheets together. A short V-O(4) bond, 1.567(5) �, indicates the presence of the cation VO3+.

Abstract The crystal structure of the title compound has been determined by X-ray diffraction methods. Due to the Lewis acidic character of the iodine substituent a “zig-zag” chain is formed via intermolecular interactions (2.933(4) A) between iodine and oxygen atoms of theocarbamate moiety. A three-dimensional network is formed through hydrogen-bridging (2.04 A) between NH-groups and the oxygen atoms of the neighbouring carbamate group of the next molecule.

Abstract The molecular structure of the 1-ethyl-3-methyl-1-alumina-indane dimer has been determined from single crystal X-ray data collected by counter methods. The compound crystallizes in the monoclinic space group C2h5-P21/c with a = 14.621(2), b = 8.3967(3), c = 8.7516(5) Å, β = 107.998(4)°, Z = 2 and dc = 1.15 gem-3 . Refinement converged with an R value of 0.037 for the 1836 reflections with I > 3 σ (I). The crystals are composed of discrete dimeric molecules possessing crystallographic 1̄ (Ci) symmetry. Each Al atom bonds to an ethyl C atom, 1.964(2) Å, as well as to alkyl 1.974(2) and aryl 2.168(1) Å C atoms of one monomer and, surprisingly, to the aryl C atom 2.104(1) Å, of the inversion related monomer. The Al-Al′ distance in the dimers is 2.6639(7) Å.

Abstract The complex between the polyether ligand 1,11-bis(tropolone)-3,6,9-trioxaundecane and RbI crystallizes in space group P21/c with cell dimensions a = 11.383(4), b = 14.493(5), c = 16.122(6) Å and β = 111.02(5)° with Z = 4. The structure was solved on the basis of 3734 X-ray reflections measured on a diffractometer with CuKα-radiation and refined to an R of 0.101. The polyether wraps around the Rb+ in a circular structure. One of the tropolone rings is elevated in order to avoid collision. Rb+ is located 1.224(6) Å above the plane formed by five oxygen atoms of the ligand, it is coordinated to I -(3.666(2)Å) and to all oxygens. The Rb+ ··· O distances of the least electronegative “ester oxygens”, 3.14(1) Å and 3.18(1) Å are significantly longer compared to the other Rb+···O distances in the range 2.81(1) Å to 3.08(1) Å. The conformation about the C-C and C-O bonds of the ligand are gauche and trans as generally found in such molecules. The two tropolone seven-membered rings are slightly non-planar and display an envelope-type structure.
