摘要

Crystals of CuNb(pyz)(2)OF5 . (pyz)(H2O) (1) and [Cu(pyz)(2.5)](+)[NbF6](-) . (pyz) (2) were grown (150 degrees C and autogeneous pressures) from CuO, 1/2(Nb2O5), (HF), pyridine, and H2O in excess pyrazine. Light blue single crystals of (1) are orthorhombic, crystallizing in space group Cccm (No. 66), with a = 14.547(1) Angstrom, b = 16.135(2) Angstrom, c = 13.803(2) Angstrom, and Z = 8. The structure of (1) contains corner shared [Cu(pyz)(4/2)F-2/2](+), [Cu(pyz)(4/2)O-2/2], and [NbF4O1/2F1/2](-0.5) octahedra. Orange crystals of (2) are monoclinic, crystallizing in space group C2/c (No.15), with a = 11.792(8) Angstrom, b = 17.123(3) Angstrom, c = 17.051(5) Angstrom, beta = 90.04(4)degrees, and Z = 8. The structure of (2) contains puckered rings of corner shared [Cu(pyz)(pyz)(3/2)](+) tetrahedra and isolated [NbF6](-) anions within the rings. [References: 43]
