Abstract
The crystal structures of hexa-mu -propionato-1:2 kappa O-6:O';-1:3 kappa ( 6) O:O'-diquinoline-2 kappaN,3 kappaN-calcium(II)dizinc(II), [CaZn2 (C3H5O2 )(6)(C9H7N)(2)], and hexa-mu -pivalato-1:2 kappa O-6:O';-1:3 kappa O-6:O'-d iquinoline-2 kappaN,3 kappaN-calcium(II)dicobalt(II), [CaCo2 (C5H9O2)(6)(C9 H7N)(2)], are described. Both contain a linear array of one Ca-II ion and t wo M-II (M= Zn, Co) ions connected by two sets of three carboxylate ligands in syn-syn bridging modes. The distorted tetrahedral geometry around the M -II ion is completed by a quinoline N atom. The central Ca-II ion occupies a crystallographic inversion centre and is octahedrally coordinated by six carboxyl O atoms in each structure. The Zn-II . . . Ca-II and Co-II . . . C a-II distances are 3.8504 (9) and 3.7929 (5) Angstrom, respectively.
