N2 - Four new complexes of fluoro-phenyl-acrylic acids (E)-3-(3-fluoro-phenyl)- acrylic acid (L1) [Mn3(L1)6(L2)2]·H 2O·CH3CN (1), [Zn2(L1) 4(L3)]n (2), [Mn(L1)2(H2O) 2]n (3) and [Co(L1)2(H2O) 2]n (4) (L2=1,10-phenanthroline, L3=4,4′-bipy) have been synthesized based on the molecular design and research of halogenhalogen interactions (especially fluorofluoro contact). The structure analyses reveal that complex 1 is a trinuclear complex, which is blocked by L2. Complex 2 is a 1D chain bridged through L3. Complexes 3 and 4 exhibit 2D grid like metalorganic framework structures through carboxylato bridge ligand. Variable-temperature magnetic measurements showed an antiferromagnetic interaction between Mn(II) ions and between Co(II) ions in complexes 3 and 4, respectively. A short C-F...F-C contact with a distance of 2.953 was found between the trinuclear coordination compound 1.
