Abstract
New magnesium tetrafluoroborate complexes with oxalic (ODH), malonic (MDH), succinic (SDH), adipic (ADH), phthalic (PDH) and terephthalic (TDH) dihydra-zides have been synthesised and investigated by elemental analyses, magnetic, conductance and IR spectral measurements. The complexes are diamagnetic with some evidence of polarisation paramagnetism. They have been assigned octahedral stereochemistry with any two of the carbonyl, amino and amide groups as the possible coordination sites.
