The reaction between K-4[Mo-IV(CN)(8)](.)2H(2)O and [Cu(L)](ClO4)(2) (L=3,10-dipropyl-1,3,5,8,10,12-hexaazacyclotetradecane) gives a novel three-dimensional cyano-bridged coordination compound [Cu(L)](2)[Mo(CN)(8)](.)2.5H(2)O (1). The thermal and magnetic behaviors of compound 1 have been investigated. X-ray single-crystal structure determinations reveal that the Mo-IV centers in 1 adopt a distorted square antiprism geometry, while the Cu-II centers in 1 adopt an elongated octahedral geometry. Each Mo-IV coordinated via four cyano groups to four Cu-II. Variable-temperature magnetic susceptibility measurements reveal that there is negligible magnetic interaction between the Cu-II centers in compound 1.
