摘要：

Heteronuclear complexes containing Co(III) and Cr(VI) are formed on reaction of [Co(en)(2)(OH)(OH2)](2+) or [Co(tren)(OH)(OH2)](2+) cations with CrO42-. TWO types of complexes were isolated: 1. Complexes with two trans chromate ligands at Co; namely Li[Co(en)(2)(CrO4)(2)].5 H2O (1a) and K[Co(en)(2)(CrO4)(2)] (Ib). 2. Complexes having a cyclic structure with two CrO4 bridges between two cis-Co(en)2 or Co(tren) units, namely [Co-2(en)(4)(CrO4)(2)]Cl-2 (2a), [Co-2(en)(4)(CrO4)(2)]Br-2 (2b) and [Co-2(tren)(2)(CrO4)(2)](ClO4)(2) (3). The molecular structures have been confirmed by X-ray methods, The molecular conformations adopted by the complexes in the solid state are stabilized by intramolecular hydrogen bonds.
