摘要：
Manganese(II) bis(4,4,4-trifluoro-1-phenylbutane-1,3-dionate) complexes with pyridin-4-one (pyon), 3-hydroxypyridin-2-one (hpyon), 1-fluoropyridine (pyF) and methanol were prepared and the solid-state structures were determined by single-crystal X-ray analysis. The coordination of the metal center in all complexes was found to be octahedral. In compounds [Mn(tfpb)(2)(pyon)(2)] (1) and [Mn(tfpb)(2)(hpyon)(2)] (2) extended hydrogen bonding is present facilitating the formation of a three-dimensional supramolecular structure in 1 and a layered structure in 2 through N-H center dot center dot center dot O hydrogen bonding enhanced by C-H center dot center dot center dot O interactions as well as C-F center dot center dot center dot pi interactions. In [Mn(tfpb)(2)(pyF)(2)] (3) a layered structure is formed through C-H center dot center dot center dot O and C-H center dot center dot center dot F interactions as well as pi center dot center dot center dot pi and C-F center dot center dot center dot pi interactions. In [Mn(tfpb)(2)(MeOH)(2)] (4) a layered structure is formed through a combination of O-H center dot center dot center dot O and C-F center dot center dot center dot pi interactions.
