Pseudohalogeno Metal Compounds. LXXVIII. Structures of Planar and Tetrahedral Tetrafulminato Metal Complexes: [N(C3H7)4]2 [Ni(CNO)4], [N(C3H7)4]2 [Pt(CNO)4], and [N(C3H7)4]2 [Zn(CNO)4] The crystals contain the tetrafulminatometallates of an ideal square planar structure ([Ni(CNO)4]2–, [Pt(CNO)4]2–) with D4h symmetry at the nickel and platinum atom and a tetrahedron ([Zn(CNO)4]2–) with perfect Td symmetry at the zinc atom and with linear C≡N–O ligands. The metal carbon bonds (Ni–C: 187 pm, Pt–C: 200 pm, Zn–C: 201 pm) of the metal fulminates are very close to those of the corresponding cyano complexes. In the crystals the anions ([Ni(CNO)4]2–, [Pt(CNO)4]2–, [Zn(CNO)4]2–) are separated by the cations ([N(C3H7)4]+) which explains the thermal stability of these compounds. 相似文献
