Synthesis and crystal structure of two polydimensional molecular architectures from cobalt(II), copper(II) complexes of 2,4-diamino-6-pyridyl-1, 3,5-triazine

Abstract

Two new Co(II) and Cu(II) complexes of 2,4-diamino-6-pyridyl-1,3,5-triazine (ptzda) have been synthesized and structurally characterized. Crystal structure studies reveal that Co atom is six-coordinated by four nitrogen atoms from four dicyanamide anions and the other two nitrogen atoms from 2,4-diamino-6-pyridyl- 1,3,5-triazine and each cobalt atom are connected by two [N(CN) 2]- anions to form an infinite double-stranded bridge fashion to give 2D ladder-like motifs. Whereas, Cu atom is five-coordinated by two nitrogen atoms from two dicyanamide anions and the other two nitrogen atoms from 2,4-diamino-6-pyridyl-1,3,5-triazine and each copper atom is connected by one methanol to form an infinite double-stranded bridge fashion to give 1D ladder-like motifs.
