The first one-dimensional coordination polymer containing O–H⋯F–Ni hydrogen bonding: crystal structure of [Ni3(dpa)4F2][Ni3(dpa)4(H2O)2](BF4)2·2CH3OH

The one-dimensional coordination polymer, [Ni3(dpa)4F2][Ni3(dpa)4(H2O)2](BF4)2·2CH3OH (dpa−=bis(2-pyridyl)amido ligand), has been constructed. The title complex crystallizes in the triclinic system, space group P1̄, 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.
