and IR spectroscopy. 1, 4 and 5 display (4,4)-connected 3-D frameworks which all can be simplified into the Schlafli symbol of (42·63·8) with sra topology, while 2 is also a (4,4)-connected 3-D network which has the Schlafli symbol of (42·84) with pts topology. 3 exhibits a 2-D structure with 3,4L83 topology and 6 is a 1-D chain structure. The fluorescent properties of 1–3 and 5 have been studied in
