چکیده
The structure of the title compound, [Cu(2)I(2)(C(44)H(32)P(2))(2)]·0.67H(2)O, has been determined because of its inter-esting catalytic and optical features. The mol-ecule, which has non-crystallographic C2-symmetry, consists of a core structure of two Cu(I) ions, bridged by two iodide ions. Each Cu(I) ion is also coordinated by one equivalent of the chiral bidentate (R)-BINAP ligand [BINAP = 2,2'-bis-(diphenyl-phosphan-yl)-1,1'-binaphth-yl]. Thus, both cations show a distorted tetra-hedral geometry being surrounded by two I atoms and two P atoms from the (R)-BINAP ligands. The complex consists of isolated butterfly-shaped mol-ecules featuring an angle of 146.11 (2)° between adjacent CuI(2) planes. The structure displays intra-molecular C-H⋯I hydrogen bonding and contains disordered water. The absolute configuration of this chiral complex was determined by anomalous dispersion effects.

In the centrosymmetric dinuclear title complex, [Cu(2)I(2)(C(22)H(16)N(2)O(4))(2)], the Cu(I) atom is coordinated in a distorted tetra-hedral geometry by an N,N'-bidentate dimethyl 2,2'-biquinoline-4,4'-dicarboxyl-ate ligand and two symmetry-related I atoms, which act as bridges to a symmetry-related Cu(I) atom. The distance between the Cu(I) atoms within the dinuclear unit is 2.6723 (11) Å.
