Popis:	A series of new lipophilic platinum(II) complexes of the type [Pt(HPIP)L2] and [Pt(HPIP)L] (where HPIP = homopiperazine; L = acetate, propionate, butyrate, pentanoate, hexanoate, heptanoate, octanoate, nonanoate, decanoate, undecanoate, laureate, tridecanoate, myristate, pentadecanoate, palmitate, or heptadecanoate; and LL = oxalate, or tartronate) were synthesized and characterized by elemental analysis, IR, 13CNMR, and 195Pt NMR. In addition, the crystal structure of a representative complex [PtII(HPIP)(pentadecanoate)2], was determined by X-ray diffraction. The crystals were monoclinic, space group P21/c, with a = 28.212(6)A, b = 3.661(3)A, c = 10.218(2)A, and Z = 4. A total of 3940 reflections were collected, and the structure refined to R1 = 0.0522 and wR2 = 0.1333. The slightly distorted square plane of the platinum included the amino groups of the HPIP molecule in cis positions and oxygens from two monodentate pentadecanoates. The HPIP molecule was in a boat conformation and formed five- a...
