The first one-dimensional coordination polymer containing O–H⋯F–Ni hydrogen bonding: crystal structure of [Ni 3(dpa) 4F 2][Ni 3(dpa) 4(H 2O) 2](BF 4) 2·2CH 3OH

Abstract

The one-dimensional coordination polymer, [Ni 3(dpa) 4F 2][Ni 3(dpa) 4(H 2O) 2](BF 4) 2·2CH 3OH (dpa −=bis(2-pyridyl)amido ligand), has been constructed. The title complex crystallizes in the triclinic system, space group P 1 ̄ , with a=11.5966(1), b=19.5609(2), c=20.1509(2) Å, α=79.5672(4), β=75.4196(4), γ=76.2199(5)°, Z=2. The rare type hydrogen bonding of O–H⋯F–Ni links the two kinds of the trinickel metal string complexes as building blocks.
