Book Description

Polyoxometalates (abbreviated as POMs); also known as early-transition metal-oxygen anion clusters; is a large and rapidly growing series of inorganic compounds. POMs can be generally divided into two subclasses: isopolyoxometalates(IPOMs) and heteropolyoxometalates (HPOMs). The former refers to a class of isopoly compounds which contain the skeletal transition metal cations and oxide ions of the same metal element. In contrast; the latter one; known as heteropoly compounds (HPCs) as well; contains both heteroatom and coordination atoms. This book reviews properties of POMs; their structure and also their synthesis.
