AB  - The  complexes  of  Mn (II)  aminobenzoates  of  the  form [Mn(ABzt)<SUB>2</SUB>X<SUB>2</SUB>], {Abzt = o-NH<SUB>2</SUB>C<SUB>6</SUB>H<SUB>4</SUB>COO<SUP>-</SUP> X = C<SUB>6</SUB>H<SUB>5</SUB>NH<SUB>2</SUB>, C<SUB>6</SUB>H<SUB>5</SUB>NHCH<SUB>3</SUB>, C<SUB>6</SUB>H<SUB>5</SUB>N(CH<SUB>3</SUB>)<SUB>2</SUB> C<SUB>6</SUB>H<SUB>5</SUB>N and p-NH<SUB>2</SUB>C<SUB>5</SUB>H<SUB>4</SUB>N} have been synthesized and characterized by microanalysis room temperature magnetic susceptibility measurements infrared and electronic reflectance spectral studies. In the complexes studied, some weak bands were observed in the region 26,000-29,000 and 18,000-19,000 cm <SUP>1</SUP>. These have been assigned to the <SUP>6</SUP>A<SUB>1g</SUB>(G)  <SUP>4</SUP>T<SUB>2g</SUB>(G)and <SUP>6</SUP>A<SUB>1g</SUB>(G)  <SUP>4</SUP>T<SUB>1g</SUB>(G) transitions, respectively. This pair is highly indicative of an octahedral geometry.
