During attempts to synthesize new platinides in the ternary system Sr–Al–Pt, single crystals of SrAl 5 Pt 3  and Sr 2 Al 16 Pt 9  were obtained from a reaction of the elements with the nominal composition Sr 4 Al 13 Pt 9 . Both orthorhombic structures were refined based on single crystal x-ray diffraction data (SrAl 5 Pt 3 :  Pnma , Wyckoff sequence  c   9 ,  a  = 2065.04(7),  b  = 413.74(1),  c  = 738.98(3) pm,  wR 2 = 0.0310, 867  F   2  values, 56 variables; Sr 2 Al 16 Pt 9 :  Immm , Wyckoff sequence  l   4   j   2   ihga ,  a  = 416.69(2),  b  = 1193.53(6),  c  = 1832.38(9) pm,  wR 2 = 0.0517, 671  F   2  values, 49 variables); full atomic ordering was observed in both cases. In order to analyze the bonding situation of these new platinides, quantum-chemical calculations were conducted. According to density functional theory both compounds are polar intermetallics with high negative charges on the Pt atoms and covalently bonded [Al 5 Pt 3 ]/[Al 16 Pt 9 ] networks showing strong Pt–Al alongside of weak Al–Al and Pt–Pt bonding.
