Abstract
Crystals of CuNb(pyz)2OF5·(pyz)(H2O) (1) and [Cu(pyz)2.5]+[NbF6]-·(pyz) (2) were grown (150°C and autogeneous pressures) from CuO, 1/2(Nb2O5), (HF)x·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) Å, b = 16.135(2) Å, c = 13.803(2) Å, and Z = 8. The structure of (1) contains corner shared [Cu(pyz)4/2F2/2]+, [Cu(pyz)4/2O2/2], 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) Å, b = 17.123(3) Å, c = 17.051(5) Å, β = 90.04(4)°, 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.
