Three Novel Transition Metal with Ethylenediamine Complex Template Polyborates [Pt(en)3]4 [B5O6 (OH)4] Cl15, [Rh(en)3][B5O6 (OH)4]3∙ 10H2O, and [Zn(en)3] [B6O7 (OH) 6]· 2H2O have been Synthesized and Characterized by Elemental Analysis, FT-IR, H, 13C, 11B - NMR, TGA-DSC, Powder X-ray Diffraction and Magnetic Properties

Abstract

Three new polyborate compounds [Pt(en)₃]₄[B₅O₆(OH)₄]Cl₁₅(1), [Rh(en)₃][B₅O₆(OH)₄]₃∙10H₂O(2), and [Zn(en)₃][B₆O₇(OH)₆]·2H₂O (3)have been prepared. The new compounds have been identified by elemental analysis, FT-IR, H, ¹³C, ¹¹B - NMR, TGA-DSC, powder X-ray diffraction and magnetic properties. The three new compounds are consisting of transition metals (platinum (IV), rhodium (III), and zinc (II)) cations, polyborate ([B₅O₆ (OH)₄]^-and [B₆O₇(OH)₆]^2-) anions, and lattice water molecules.

Keywords: polyborate, zinc (II), platinum (IV), rhodium (III).
