Abstract It has been found that, in the crystal of Li(+)589-[Cr(en)3] (d-tart)2·3H2O, the complex cation Λ-δδδ-[Cr(en)3]3+ is sandwiched between two crystallographically different d-tartrate anions. The centers of the both anions are located on the threefold axis of the octahedral complex cation and the characteristic local “[Cr(en)3] (d-tart)2” block is formed. The structural feature of this local block bears a close resemblance to that found in (+)589-[Co(en)3] Br·d-tart·5H2O.
