Abstract

Two isomorphous bimetallic polymeric transition metal dicyanamides [Cu(OAc)(bpy)₂][Mn(dca)₃(H₂O)] (1) and [Zn(OAc)(bpy)₂][Mn(dca)₃(H₂O)] (2) (bpy = 2,2'-bipyridine, dca = dicyanamide) have been synthesized and characterized. Each consists of Mn-dca ladder chain anions and chelated cations of the other metal, Cu or Zn. The novel ladder-like [Mn(dca)₃(H₂O)^-]_n chains build a pseudo-(4,4) sheet through hydrogen bonds between the chains. The [M(OAc)(bpy)₂]⁺ (M = Cu, Zn) cations form a layer through weak C-H⋯O hydrogen bonds and φ-φ interactions. These oppositely charged sheets construct a sandwich structure by conventional O-H⋯O hydrogen bonds and weak C-H⋯C/N/O interactions. The Mn²⁺ ions are octahedrally coordinated in both compounds, while Cu²⁺ and Zn²⁺ ions have distorted octahedral environments. Magnetic investigation shows that the coupling interaction between Mn²⁺ centers of the ladder Mn-dca chains is weak antiferromagnetic.
