A novel cobalt (I) coordination polymer with mixed thiocyanate and quinoline ligands: Crystal structure, magnetism and luminescent properties

• Synthesized a new Co(I) 1D coordination polymer.
• Crystal structure analyses and discussion for the compound.
• The luminescent properties and magnetic properties were investigated.

A new Co(I) one-dimensional coordination polymer [Co(SCN)(ql)]n (ql = quinoline) (1) has been synthesized and characterized by IR, elemental analysis, TG technique and X-ray crystallography. Co(I) atom has a distorted trigonal pyramidal N2S2 (1) environment with two S atoms and one N atom from three μ-1,1,3-thiocyanate bridge ligands and one N atom from ql ligand. Two S atoms from two μ-1,1,3-SCN− bridging ligands bridge two centers to obtain bimetallic 4-membered ring. Adjacent 4-membered rings are linked by a pair of μ-1,1,3-SCN− bridging ligands to form a 1D stair-case like chain. The luminescent properties and magnetic properties of the polymer 1 were investigated in the solid state.
