a The SCXRD structure of C2H2-loaded Al-PyDC viewed along the c axis, indicating two types of C2H2 binding sites. b Illustration of C2H2 binding site-I, (c) C2H2 binding site-II, and (d) dense packing of C2H2 molecules within Al-PyDC. e The C2H6 binding site and (f) C2H4 binding site in gas-loaded Al-PyDC, determined by SCXRD analysis.
