Crystal structure of di-µ-iodido-bis-{[1,3-bis-(2,6-diiso-propyl-phen-yl)imidazol-2-yl-idene]lithium}.

In the title binuclear complex, [Li2(C27H36N2)2I2], the unique Li(I) cation is coordinated by two iodide anions and one yl-idene C atom from a 1,3-bis-(2,6-diiso-propyl-phen-yl)imidazol-2-yl-idene ligand in a distorted trigonal-planar geometry. The two symmetry-related iodide anions bridge two Li(I) cations, forming an inversion dimer in which the Li2I2 plane is nearly perpendicular to the imidazol-2-yl-idene ring, with a dihedral angle of 85.5 (3)°. No hydrogen bonding is observed in the crystal.

catena-Poly[[bis-(methanol-κO)bis-(pyridine-κN)nickel(II)]-µ-tetra-fluoro-terephthalato-κO:O'].

In the title compound, [Ni(C(8)F(4)O(4))(C(5)H(5)N)(2)(CH(4)O)(2)](n), the Ni(II) ion is located on an inversion center and is coordinated by four O atoms [Ni-O = 2.079 (4) Å] from two tetra-fluoro-terephthalate ligands and two methanol mol-ecules, and by two N atoms [Ni-N = 2.127 (4) Å] from two pyridine ligands in a distorted octa-hedral geometry. The Ni(II) ions are connected via the tetra-fluoro-terephthalate anions into a one-dimensional chain running along the crystallographic [011] direction.

catena-Poly[[tris-(pyridine-κN)copper(II)]-µ-tetra-fluoro-terephthalato-κO:O].

In the title compound, [Cu(C(8)F(4)O(4))(C(5)H(5)N)(3)](n), the Cu(II) atom, lying on a twofold rotation axis, is five-coordinated by two O atoms from two tetra-fluoro-terephthalate ligands and three N atoms from three pyridine ligands in a distorted trigonal-bipyramidal geometry. Adjacent Cu(II) atoms are connected via the bridging tetra-fluoro-terephthalate ligands into a one-dimensional chain running along the [101] direction.
