A seven-platinum cluster, 1, Pt7(2,6-Me2C6H3NC)12, was prepared by the reduction of dichloro(2,6-xylyl isocyanide)platinum(II) with sodium amalgam. The cluster 1 was characterized by single-crystal X-ray diffraction. Crystal data: space group P21/a, a = 28.565 (6) ?, b = 26.694 (25) ?, c = 15.278 (3) ?, β = 119.66 (2)°, V = 10123 ?3. The molecule contains a metal atom cluster derived from a distorted trigonal-bipyramidal unit to which two extra platinum atoms have been attached in bridging positions between one equatorial and each apical Pt atom. One of the isocyanide groups coordinates in an unusual fashion: through the C=N- group to three platinum atoms by four electrons, in such a way as to form a planar cyclic CNPt3 unit.
