Synthesis and characterization of coordination polymers of Zn(II) with 1,3-bis(4-pyridyl)propane and 4,4′-pyridine ligands

Unique tetranuclear heterometallic compound [Na2Zn2{(4-py)C(H)(NOH)}2(CH3COO)6(H2O)4].2H2O with luminescent properties

“…The acetate anion as a polydentate ligand is widely used in coordination chemistry nowadays. The generalization of modes of CH 3 COO − inclusion in coordination compounds is available [24][25][26][27][28][29][30][31][32][33]. Our search of CSD [34] revealed the commonly observed modes of the acetate anion coordination to the Zn(II) atom summarized in Scheme 2.…”

A novel one-dimensional zinc coordination polymer containing 4-methylbenzoate and 4,4-bipyridine

“…The four 4-methylbenzoate ligands link two Zn atoms to construct a dinuclear zinc building block, with a ZnÁ Á ÁZn separation of 3.188 (2) Å , which can be regarded as a supramolecular secondary building unit (SBU) or knot. The construction of the knot is similar to that of the Zn 2 (acetate) 4 unit in the infinite chains of that structure (Lee et al, 2004). Unlike the symmetrical paddlewheel arrangement typically observed in M 2 (carboxylate) 4 dimers, in (I) two of the 4-methylbenzoate ligands bridge the Zn atoms through separate O atoms, one bridges through a single O atom, and one chelates a single Zn atom only.…”

Synthesis and structural studies of [Mn(μ-bpp)2Cl2]n: a 3D coordination polymer of Mn(II) with 1,3-bis(4-pyridyl)propane

“…Recently, bpp ligands were used with nickel, cobalt, cadmium, zinc and copper ions to form *Corresponding author. E-mail: morsali_a@modares.ac.ir new metal-organic coordination polymers [33][34][35][36][37]. As a continuation of these works, we herein report the solid state structure of [Mn(μ-bpp) 2 Cl 2 ] n as a new three-dimensional coordination polymer.…”
