Diaquadi-?-formato-bis-{?-2,2'-[propane-1,3-diylbis(nitrilo-methanylyl-idene)]diphenolato}cadmium(II)dinickel(II) dihydrate.


ABSTRACT: In the centrosymmetric title compound, [CdNi(2)(C(17)H(16)N(2)O(2))(2)(HCOO)(2)(H(2)O)(2)]·2H(2)O, The Ni(II) cation is chelated by a 2,2'-[propane-1,3-diylbis(nitrilo-methanylyl-idene)]diphen-olate (salpn) anion, and further coordinated by a formate anion and a water mol-ecule in a distorted NiN(2)O(4) octa-hedral geometry. The Cd(II) cation, located on an inversion center, is coordinated by four deprotonated hy-droxy groups from two salpn anions and two carboxyl-ate O atoms from formate anions in a distorted octa-hedral geometry. Both formate and salpn anions bridge the Cd and Ni cations, forming a trinuclear complex. Within the salpn anion, the benzene rings are twisted to each other at a dihedral angle of 61.46?(18)°. Inter-molecular O-H?O hydrogen bonding is present in the crystal structure. The lattice water mol-ecule is disorder over two positions with an occupancy ratio of 0.75:0.25.
