K Ni Pd Pd
KPd2Ni crystallizes in the monoclinic Cm space group. K(1) is bonded in a 10-coordinate geometry to four equivalent K(1), two equivalent Pd(1), and four equivalent Pd(2) atoms. All K(1)-K(1) bond lengths are 3.18 Å. There is one shorter (3.63 Å) and one longer (3.97 Å) K(1)-Pd(1) bond length. There are a spread of K(1)-Pd(2) bond distances ranging from 3.27-3.77 Å. There are two inequivalent Pd sites. In the first Pd site, Pd(1) is bonded in a 3-coordinate geometry to two equivalent K(1) and three equivalent Ni(1) atoms. There is one shorter (1.86 Å) and two longer (2.29 Å) Pd(1)-Ni(1) bond lengths. In the second Pd site, Pd(2) is bonded in a single-bond geometry to four equivalent K(1) and one Ni(1) atom. The Pd(2)-Ni(1) bond length is 0.73 Å. Ni(1) is bonded in a single-bond geometry to one Pd(2) and three equivalent Pd(1) atoms.
