Syntheses, crystal structures, and characterization of two Mn(II) coordination polymers with bis(4-(1H-imidazol-1-yl)phenyl)methanone ligands

Two Mn(II) complexes, {[Mn(BIPMO) 2 Cl 2 ] · 2(H 2 O)} n ( 1 ) and {[Mn(BIPMO) 2 (SCN) 2 ] · 2(CH 3 OH)} n ( 2 ) (BIPMO = bis(4-(1 H -imidazol-1-yl)phenyl)methanone) with V-shaped BIPMO ligands, were synthesized and characterized by IR spectroscopy and elemental analyses along with their single-crystal X-ray diffraction analyses. The Mn(II) ions in 1 and 2 are both six-coordinated to four nitrogen atoms of four BIPMO ligands and two anions (Cl − for 1 , and SCN − for 2 ) to form a distorted octahedral geometry.
