Abstrakt:	The coordination polymer {[Cu(SiF6)(C10H8N2)2]·2C10H8N2·5H2O}n, systematic name: poly[[bis­(μ2-4,4′-bi­pyridine)(μ2-hexa­fluorido­silicato)copper(II)] 4,4′-bi­pyridine disolvate penta­hydrate], contains pores which are filled with water and 4,4′-bi­pyridine mol­ecules. As a result of the presence of these ordered species, the framework changes its symmetry from P4/mmm to P21/c. The 4,4′-bi­pyridine guest mol­ecules form chains inside the 6.5 × 6.9 Å pores parallel to [100] in which the mol­ecules inter­act through π–π stacking. Ordered water mol­ecules form infinite hydrogen-bonded chains inside a second pore system (1.6 × 5.3 Å free aperture) perpendicular to the 4,4′-bi­pyridine channels. [ABSTRACT FROM AUTHOR]
