Solvothermal synthesis with manganese nitrate, p-biphenyldicarboxylic acid, and three different solvents resulted in three new metal–organic framework materials: Mn(C14H8O4)(C3H7NO)2/3 (1), Mn2(C14H8O4)3/2(CHO2) (2), and Mn3(C14H8O4)3(C4H9NO)4 (3).

Depending on the number of interstitial solvent molecules, n, crystals of the linear chain compound Co-3(dipyridylamide)(4)Cl-2 center dot nCH(2)Cl(2) adopt either symmetrical or unsymmetrical metal chain structures. We explore here the possible reas

Two isostructural metal organic framework (MOF) structures have been synthesized by solvothermal methods and examined by single-crystal X-ray diffraction. A microcrystal of 2C4H12N+[Co3(C8H4O4)4]2−·3C5H11NO (1) was investigated at T = 120 K using

A new magnetic metal organic framework material has been synthesized, Mn3(C8O4H4)3(C5H11ON)2, 1. Magnetic susceptibility measurements from 2 to 400 K reveal anti-ferromagnetic ordering at approximately 4 K and a total magnetic moment of 6.0 micro(B).
