Rhodium oxide Specification

The Rhodium(III) oxide, with the CAS registry number 12036-35-0 and EINECS registry number 234-846-9, has the systematic name of oxo-(oxorhodiooxy)rhodium. It is a kind of yellow powder, and belongs to the following product categories: Inorganics; RhodiumMetal and Ceramic Science; Catalysis and Inorganic Chemistry; Chemical Synthesis; Oxides; Rhodium. And the molecular formula of this chemical is Rh₂O₃. What's more, the Rh₂O₃ has been found in two major forms. The hexagonal form has the corundum structure, and it transforms into an orthorhombic structure when heated above 750 °C.

The physical properties of Rhodium(III) oxide are as followings: (1)#H bond acceptors: 3; (2)#H bond donors: 0; (3)#Freely Rotating Bonds: 2; (4)Polar Surface Area: 43.37 Å².

Preparation: (1)Rh metal powder is fused potassium hydrogen sulfate. Adding sodium hydroxide results in hydrated rhodium oxide, which upon heating converts to Rh₂O₃; (2)Rhodium oxide thin films can be produced by exposing Rh layer to oxygen plasma; (3)Nanoparticles can be produced by the hydrothermal synthesis.

You should be cautious while dealing with this chemical. It irritates to eyes and skin, and if contact with combustible material, it may cause fire. Therefore, you had better take the following instructions: Wear suitable gloves and eye/face protection, and in case of contacting with eyes, rinse immediately with plenty of water and seek medical advice; Keep away from combustible material; Do not breathe dust; Avoid contact with skin and eyes.

You can still convert the following datas into molecular structure:
(1)SMILES: O=[Rh]O[Rh]=O
(2)InChI: InChI=1/3O.2Rh/rO3Rh2/c1-4-3-5-2
(3)InChIKey: YRUZFXVGBSPFRV-DUCYPWGEAJ
