These chemicals are expected to form gold-bridged dimers in a manner similar to titanium(IV) hydride. [15] Gold(II) compounds are usually diamagnetic with Au–Au bonds such as [Au(CH 2) 2 P(C 6 H 5) 2] 2 Cl 2. The evaporation of a solution of Au(OH) 3 in concentrated H 2 SO 4 produces red crystals of gold(II) sulfate, Au 2 (SO 4) 2.
Au 5 Al 2 typically forms at 95% of Au and 5% of Al by mass, its melting point is about 575 °C, which is the lowest among the major gold-aluminum intermetallic compounds. AuAl 2 is a brittle bright-purple compound, with a composition of about 78.5% Au and 21.5% Al by mass.
Dutch White – a pigment, formed from one part of white lead to three of barium sulfate. BaSO 4; Flowers of antimony – antimony trioxide, formed by roasting stibnite at high temperature and condensing the white fumes that form. Sb 2 O 3; Fool's gold – a mineral, iron disulfide or pyrite; can form oil of vitriol on contact with water and air.

Aluminium also bears minor similarities to the metalloid boron in the same group; AlX 3 compounds are valence isoelectronic to BX 3 compounds (they have the same valence electronic structure), and both behave as Lewis acids and readily form adducts. [4] Additionally, one of the main motifs of boron chemistry is regular icosahedral structures ...

Aluminium nitrate cannot be synthesized by the reaction of aluminium with concentrated nitric acid, as the aluminium forms a passivation layer. Aluminium nitrate may instead be prepared by the reaction of nitric acid with aluminium(III) chloride. Nitrosyl chloride is produced as a by-product; it bubbles out of the solution as a gas.
