Abstract :In this study, two heterometallic transition metal complexes with the formulas [CoK$_{4}insert ignore into journalissuearticles values(\mu _{10}$-C$_{6}$H$_{5}$O$_{7});_{2}$]$_{n}$ and [CdKinsert ignore into journalissuearticles values($\mu _{8}$-C$_{6}$H$_{5}$O$_{7});insert ignore into journalissuearticles values(\mu $-H$_{2}$O);insert ignore into journalissuearticles values(H$_{2}$O);]$_{n}$ were synthesized as crystalline compounds. The structures of\textbf{ }these crystalline metal complexes were characterized by their spectral analyses insert ignore into journalissuearticles values(FT-IR, FT-Raman, thermal analysis, magnetic properties, and single-crystal X-ray diffraction techniques);. According to the spectral data of the new metal complexes obtained, both metal complexes are in the monoclinic crystal system and in the P2$_{1}$/c and P2$_{1}$ space groups, respectively. The asymmetric unit of the metal complex [CoK$_{4}insert ignore into journalissuearticles values(\mu _{10}$-C$_{6}$H$_{5}$O$_{7});_{2}$]$_{n}$ contains one Coinsert ignore into journalissuearticles values(II); ion, two potassium cations, and one insert ignore into journalissuearticles values(C$_{6}$H$_{5}$O$_{7});$ citrate ligand, whereas that of the asymmetric unit of the metal complex [CdKinsert ignore into journalissuearticles values($\mu _{8}$-C$_{6}$H$_{5}$O$_{7});insert ignore into journalissuearticles values(\mu $-H$_{2}$O);insert ignore into journalissuearticles values(H$_{2}$O);]$_{n}$ contains one Cdinsert ignore into journalissuearticles values(II); ion, one potassium cation, one insert ignore into journalissuearticles values(C$_{6}$H$_{5}$O$_{7});$ citrate ligand, and two coordinated water molecules.
