Three novel compounds have been synthesized and structurally characterized: [1,10-Hphen](2)Pt(CN)(4)center dot 2H(2)O (1a) space group P2(1)/n, a = 8.73070(17) , b = 15.4609(2) , c = 9.82661(19) , beta = 103.252(2)A degrees; [2,2'-Hbipy](2)Pt(CN)(4)center dot 2H(2)O (1b) space group P2(1)/n, a = 7.0859(14) , b = 12.940(2) , c = 13.7486(19) , beta = 100.708(16)A degrees; K(2)[Pt(CN)(4)]center dot 2phen (phen = 1,10-phenanthroline) (2) space group P2(1)/c, a = 8.1393(4) , b = 20.4050(9) , c = 8.4085(4) , beta = 105.284A degrees. All three structures contain isolated [Pt(CN)(4)](2-) ions and they all illustrate the absence of Pta <-Pt interactions due to the presence of bulky cyclic amines or ammoniums. The structures of 1a and 1b contain large organic cations, 2,2'-bipyridinium and 1,10-phenanthrolinium, respectively while compound 2 contains neutral 1,10-phenanthroline molecules co-crystallized between the potassium tetracyanoplatinate framework.
