چکیده
In the course of substitution studies on the iron dihydrogen complex trans-[Fe(DMeOPrPE)(2)(H(2))H](BPh(4)) {DMeOPrPE = 1,2-bis-[bis-(methoxy-prop-yl)phosphino]ethane}, we discovered an unexpected transformation of the diphosphine ligand to a diphospho-nium dication without the use of any typical methyl-ating reagent. The P atoms in the dication of the title compound, C(20)H(46)O(4)P(2) (2+)·2C(24)H(20)B(-)·C(4)H(10)O, have a distorted tetra-hedral coordination with P-C(Me) distances of 1.791 (2) and 1.785 (2) Å. The P-C-C-P torsion angle about the central dimethyl-ene bridge is -168.3 (1)°.

In the title complex, {[Ag(2)(CF(3)O(3)S)(2)(C(30)H(20)N(6))]·C(6)H(6)}(n), the two independent Ag(I) ions are each coordinated by two N atoms and one O atom in a 'T-shaped' geometry. In the crystal structure, 1,2-bis-[(3-cyano-benzyl-idene)hydrazono]-1,2-diphenyl-ethane ligands act as bridging ligands and each coordinates to four Ag(I) ions, resulting in a one-dimensional chain structure.

The asymmetric unit of the title compound, C(20)H(28)N(2)O(6)S(2), contains one half-mol-ecule, related to the other half by a twofold rotation axis. The two aromatic rings of the mol-ecule make a dihedral angle of 50.91 (7)°. The O-CH(2)-CH(2)-O and N-CH(2)-CH(2)-O fragments both adopt gauche conformations, with torsion angles of 76.0 (4) and 70.4 (3)°, respectively. In the crystal, adjacent m...
