New optically active benzylmethylphenylgermylacetic acid (1) and benzylmethylphenylgermanecarboxylic acid (2) were obtained successfully by a fractional crystallization method using a-methylbenzylamine (MBA) as a resolving agent. The optical purities of both 1 and 2 were determined by NMR to be 94%. The relative configurations of 1 and 2 were also discussed.
