Two novel 3D network coordination polymers {Mn(L)<SUB>2</SUB>[Ag(CN)<SUB>2</SUB>]<SUB>2</SUB>}{Mn(H<SUB>2</SUB>O)<SUB>2</SUB>[Ag(CN)<SUB>2</SUB>]<SUB>2</SUB>} (L = 4-CNpy (<B>1</B>) or py-4-aldoxime (<B>2</B>)) (4-CNpy = 4-cyanopyridine; py-4-aldoxime = pyridine-4-aldoxime) were synthesized and characterized by using single-crystal X-ray analysis and magnetic measurements. Both complexes have two distinct octahedral manganese atoms, Mn(1) and Mn(2), linked by a [Ag(CN)<SUB>2</SUB>]<SUP>−</SUP> unit. The pyridine ring of two Ls coordinate at the apical positions of Mn(1). On the other hand, at the apical positions of Mn(2), two H<SUB>2</SUB>O are coordinated. The apical axis of Mn(1) is not parallel to the apical axis of Mn(2). Therefore, {Mn[Ag(CN)<SUB>2</SUB>]<SUB>2</SUB>} networks in <B>1</B> and <B>2</B> are distorted and form three-dimensional (3D) frameworks. There are large channels in the 3D networks; however, triple interpenetration was found in <B>1</B> and <B>2</B>. From the temperature dependence of magnetic susceptibility, there is very weak antiferromagnetic interaction between the Mn atoms bridged by a [Ag(CN)<SUB>2</SUB>]<SUP>−</SUP> unit in <B>1</B> and <B>2</B>.
