Syntheses and characterizations of tetracyanoplatinate(II) complexes with 2-pyridineethanol

Abstract

New cyanide-bridged heteronuclear polymeric complexes, [Cu(hepH) 2 Pt(μ-CN) 2 (CN) 2 ] n (1), [Zn (hepH) 2 Pt(μ-CN) 2 (CN) 2 ] n (2), and [Cd(hepH) 2 Pt(μ-CN) 2 (CN) 2 ] n (3) (2-pyridineethanol abbreviated to hepH), have been synthesized and characterized by elemental analysis, FT-IR and Raman spectroscopies, thermal analysis, and single-crystal X-ray diffraction techniques. Hydrogen bonds play very important roles in the construction of supramolecular structures. From the crystallographic data, it was determined that the crystal packings of 1-3 were composed of rare intermolecular C-H⋯Pt interactions. In addition, these complexes have π⋯π and O-H⋯N interactions.The cyanide-bridged heteronuclear polymeric complexes, [M(hepH) 2 Pt(μ-CN) 2 (CN) 2 ] n (M = Cu(II) (1), Zn(II) (2) and Cd(II) (3); hepH = 2-pyridineethanol), have been synthesized and characterized by elemental analysis, FT-IR and Raman spectroscopies, thermal analysis, and single-crystal X-ray diffraction techniques. The crystallographic analyses reveal that 1 and 2 crystallize in the triclinic *Corresponding author.

The structures of 1-3 consist of 1-D linear chains in which the M(II) and Pt(II) ions are linked by cyanide ligands. Each M(II) center exhibits a distorted octahedral coordination environment with four nitrogens from two cyanides and two hepH ligands. The 1-D chains are further linked by C-H⋯Pt and O-H⋯N hydrogen bonding interactions to construct 3-D supramolecular structures. Thermal stabilities and decomposition products of the complexes were investigated from 30 to 700°C in air.

Zinc Tetracyanoplatinate: A Reversible Luminescence‐Based Ammonia Sensor

“…Other solution‐based syntheses of ZnPt(CN) 4 have been reported, but the products not characterized. The addition of excess Na 2 Pt(CN) 4 to an aqueous solution of Zn(NO 3 ) 2 generated a white precipitate exhibiting a green luminescence; no further characterization of this product was described .…”

SYNTHESES, STRUCTURES AND PHYSICAL PROPERTIES OF CYANIDE-BRIDGED M(II)−Ni(II) BIMETALLIC COMPLEXES WITH 2-PYRIDINEETHANOL (M(II) = Fe, Co and Ni)

“…In our previous studies, we have reported the tetracyanonickelate(II), tetracyanopalladate(II) and tetracyanoplatinate(II) complexes with hepH [12][13][14]. As a part of our continuing research on cyanide complexes, herein we described the syntheses and characterizations of tetracyanonickelate(II) complexes with different metals such as Fe(II), Co(II) and Ni(II).…”

Preparation and Characterisation of the Cyano-Bridged Transition Metal Complexes Using N,N-Diethyl Thiourea as a Ligand

“…13,14 Planar cyano metal anions are widely used to design these complexes. 14,15,16,17 Especially, square-planar tetra cyanometallate(II) ions, i.e. [M(CN) 4 ] 2-(M(II) = Ni, Pd or Pt), have been widely used as building blocks of Hofmann type structures.…”
