چکیده
The title compound, [Cu2I2(CH3CN)4], exhibits a centrosymmetric Cu2I2 core [Cu⋯Cu distance = 2.7482 (11) Å], the Cu(I) atoms of which are further coordinated by four mol-ecules of aceto-nitrile. The Cu(I) atom has an overall distorted tetra-hedral coordination environment evidenced by L-Cu-L angles (L = N or I) ranging from 100.47 (10) to 117.06 (2)°. The coordination geometries of the aceto-nitrile ligands deviate slightly from linearity as shown by Cu-N-C angles of 167.0 (2) and 172.7 (2)°. In the crystal, there are no significant hydrogen-bonding inter-actions present, so the crystal packing seems to be formed predominantly by van der Waals forces.

The centrosymmetric dinuclear title compound, [Cu2I2(C2H6OS)2(C18H15P)2], represents the first example of a CuI complex ligated by an O-bound dimethyl sulfoxide ligand. In the crystal, the two tetrahedrally coordinated Cu(I) atoms are bridged by two μ2-iodido ligands in an almost symmetrical rhomboid geometry. The loose Cu⋯Cu contact of 2.9874 (8) Å is longer than the sum of the van der Waals r...

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 imid...
