摘要：
A new platinum(II) complex, C24H16N10S2Pt .3H2O, bis(4,5-diazafluorene-9-one thiosemicarbazato) platinum(II) trihydrate, has been synthesized. Crystals of it are trigonal, space group P3(2) with cell parameters of a = 10.696(4), c = 19.748(6) Angstrom and Z = 3. The ligands are coordinated to the platinum(II) atom by two imino nitrogen atoms N(3) and N(8), and two sulfur atoms S(1) and S(2) forming a rigid molecular tweezers maintained by intramolecular pi-pi stacking. Detailed crystal structure analyses exhibit that the one-dimensional 3(2) screw robust supramolecular aggregate was achieved by intermolecular pi-pi stacking interaction between the extensive delocalization rr-system ligands via self-assembly and the aggregates were linked by hydrogen bonding.
