The com pound is hexagonal, a — 9.687(2) and c = 19.336(6) A, space group C |-P 6 i, Z — 6 . The given atom ic coordinates represent the ab solu te configuration. The nearly square planar P t(C N)42~ groups form a helix w ith respect to th e c axis. The distance betw een n eig h ­ bouring P t atom s in th e helix is 3.543(1) Ä. The norm al o f th e P t(C N)42~ group is tilted about 15 deg to the c axis leading to a considerable overlap o f m eta l orbitals w hich is suggested from optical em ission studies. T he protons o f th e wrater m olecules form hydrogen bonds to nitrogen atom s o f different helices. B oth Cs atom s have similar sevenfold coordination.
