Abstract
The reaction of 1,5,5'-trimethyl-1H,1'H-3,3'-bipyrazole (Hbpz) with copper and manganese salts (Cu(BF4)(2)center dot 6H(2)O, MnCl2 center dot 4H(2)O and Mn(NCS)(2)) leads to the formation of three mononuclear coordination complexes [Cu(Hbpz)(3)](BF4)(2) (1), [Mn(Hbpz)(2)Cl-2]center dot CH3CN (2) and [Mn(Hbpz)(2)(NCS)(2)]center dot Et2O (3). These compounds have been characterized using single crystal X-ray diffraction and infrared spectroscopy. The single crystal structures of 1, 2 and 3 are discussed in the context of the effect of hydrogen bonding functionalities and counter anions on the supramolecular structural diversities observed in these new coordination complexes.
