Abstract
Two new coordination polymers, [CoL(bpp)]n (1) and [MnL(bipy)]n·0.25nH2L·0.5nH2O (2) (H2L = 1,3-adamantanediacetic acid, bpp = 1,3-bis(4-pyridyl)propane, bipy = 4,4′-bipyridine), were synthesized and characterized by single crystal X-ray diffraction, IR spectroscopy, and thermal analysis. Complex 1 is an one-dimensional (1D) chain structure of Co(II) bridged by L2− as well as bpp. Complex 2 consists of a two-dimensional (2D) (3,6)-connected topology layer structure. Variable temperature magnetic susceptibility measurements in the range of 2–300 K reveal the existence of weak antiferromagnetic interactions in two complexes with J = −1.74 cm−1, g = 2.26 for 1 and J = −0.10 cm−1, g = 1.67 for 2.Index abstractTwo mental-organic frameworks, namely [CoL(bpp)]n (1) and [MnL(bipy)]n·0.25nH2L·0.5nH2O (2) (H2L = 1,3-adamantanediacetic acid, bpp = 1,3-bis(4-pyridyl)propane, bipy = 4,4′-bipyridine), have been synthesized based on 1,3-adamantanediacetic acid and N-donor coligand with metal ions Co(II) and Mn(II). The magnetic measurement of the two polymers reveals typical antiferromagnetism exchange.
