Özet

Two new complexes, [Cd-2(4-4'-bpy)(2)(pa)(4)] (n) center dot 0.25H(2)O (1) (pa = phenylacetate), and [Mn(4-4'-bpy)(2)(pa)(H2O)(3)]ClO4 center dot 2H(2)O, (2), have been obtained from hydrothermal reaction of Cd(NO3)(2)center dot 4H(2)O and Mn(ClO4)(2)center dot 6H(2)O with a mixture of the ligands, 2-phenylmalonic acid (2-phmalH(2)) and 4-4'-bipyridine (4-4'-bpy). The pa is formed in situ by decarboxylation of phenylmalonic acid. These complexes have been characterized by elemental analysis, FT-IR spectroscopy, thermogravimetric analysis and single-crystal X-Ray diffraction. The Cd(II) center is seven-coordinate and linked via pa ligands to form a binuclear complex in the asymmetric unit of 1. A ladder-like 1D chain of binuclear units is formed by Cd(II)-N coordination bond through 4-4'-bpy ligands. Complex 2 consists of a mononuclear manganese center based on a distorted octahedral geometry and exhibits a supramolecular structure containing hydrogen bonds and extensive pi center dot center dot center dot pi and C-H center dot center dot center dot pi interactions.
