Parts and what they mean

• Manganate, MnO₄²⁻: green, paramagnetic (मैंगनेट, MnO₄²⁻: हरा, अनुचुंबकीय) — Mn +6 = 3d¹: one unpaired electron.
• Permanganate, MnO₄⁻: purple, diamagnetic (परमैंगनेट, MnO₄⁻: बैंगनी, प्रतिचुंबकीय) — Mn +7 = 3d⁰: no unpaired electron. Its intense colour is not a d–d transition (there are no d electrons).
• Manganese at the centre (केंद्र में मैंगनीज़) — Surrounded tetrahedrally by four O atoms.
• Tetrahedral, with π-bonding (चतुष्फलकीय, π-आबंधन के साथ) — π-bonding by overlap of oxygen p orbitals with manganese d orbitals (NCERT).
