Two new benzo-[15]-crown-5 attached phenanthroline platinum(II) complexes with the gen- eral formula Pt(phen)X2, where X = Cl (1), C≡CC6H5 (2) have been synthesized, and their absorption and luminescence response towards metal ions have been studied.
A chiral complex of (R,R)-Pd was prepared by reaction of optically pure (R,R)-bis(pyrrol-2-ylmethyl-eneamino) cyclohexane ligand with Pd(OAc)2·2H2O under the base condition at room temperature. The weak intermolecular C-H···Pd interaction was found to be responsible for the homochiral M helix for-mation of the neutral,chiral,mononuclear (R,R)-Pd in the crystal packing.
