I live in Ogle a small hamlet 12 miles north west of Newcastle upon Tyne, UK. I am now retired. Initially trained as a chemist (PhD at Lancaster University some 35 years ago) I ended up making a career in IT.

My interests wiki wise are main group chemistry, structural chemistry.

I dislike editors who add material without checking it out first to establish that it has a basis in fact, who add unreferenced material, who make multiple edits instead of composing their edit in a sandbox and moving it across, who can't admit they are wrong.

In progress- awaiting RSC access to complete.

• silicon phosphate compounds /silica phosphate glasses
• Ultraphosphates
• BaPbO₃ - used in lead acid batteries
• Bi2O4 - new article? or just a mention in Bismuth?
• plumbate - metaplumbate anion - - PbO₃^2- - polymeric in solid state-
• lone pair - in Pb(II) compounds. PbO distorted PbS rock salt.
• sodium bismuthate- hydrate known- dehydrates to anhydrous ilmenite form (see Bismuth-Containing Compounds By Handong Li, Zhiming M. Wang)

Lanthanide - oxidation states - add +4 Dy in e.g. hexahalo ion from Greenwood and tetravalent state in Encyclopedia

Cerium article- little or no content on +4 state. CeCl62- anion - aqueous chem mssing dimer (recent paper)- also in Belousov - Z reaction

Dysprosium article - +4 ox state in e.g. hexahalo ions

Lutetium article - silly statement that only ox state is +3 - what about DyQ, (S, SE etc)- insulating monochalcogenides, also all the pseudo +2

Scandium (GA) - so much missing- carbides, borides, nitride, phosphide and hydrides poorly covered

Yttrium(FA) - hardly any chemistry there- all based on Daanes excellent 1968 publication

• Sulfur (C) sulfur oxo-acids nedds expansion, chemical properties missing double bonding, hard soft acid base; length of sulfide bridges in cured rubber, no mention of rubber vulcanization in lede; oxide section a bit light; no interchalcogen compounds
• Compounds of fluorine- misquote of NNG and the old explanation of partial double bond charcter for Cl₂- using d orbitals
• Lone pair - LPBWE and recent view on stereoactivity

Peroxophosphoric acids, peroxophophates

• Boric acid missing H2O2 to give peroxoboric acid; hypohalito complexes
• lead compounds- PbO₂ reasons for metallic nature-per Pykko and egdell, compounds of lead article- check out the four valent organo reason
• Magensium low valent-- Cameron Jones group using Mg2complexes as mild reducing agents - see ditin paper by jones pdf

Carbonates

• Carbonate missing solubility summary of salts, missing carbanato complexes (neutral and other), missing occurence of M^III carbonates for larger cations
• various carbonate articles- missing structural information e.g. magnesium carbonate also lot of chem is unreferenced and incomplete

Hydrides- alloys or compounds

• address chromium, iron articles and correct the TiH₂ article when alloy furore resolved

New articles

• gallium(I) oxide (suboxide) missing

Corrections/additions

• Lead dioxide- non-stoichiometry metallicity (paper) (Egdell has published too many!)- clarify structures- preps of different forms- form in lead-acid batteries etc etc
• GeO2- image of rutile like stishovite chem box says hexagonal- which polymorph (hex or teragoanal) is the thermo favored?
• plumbate- corrections - metaplumbates do not contain PbO32-, orthoplumbates some contain island PbO4 others more complex
• thiophosgene - structure and dimerisation (Wells and paper)
• Atomic carbon - add carbido complexes/cluster (Wiberg p 1562) (Steinborn Fundamentals of organometallic catalysis) Wades rule for clusters C may hypervalent carbo-cations CH_n⁺ bonding is between the Au and C, metal metal bonding negligible so no cluster , and no Wade's rules explanation.
• aluminothermic reaction aluminothermic process thermite all related missing content.
• aluminium fluoride mentions aluminium production but needs expanding hall-heroult process
• All of the hydride articles!
• non-stoichiometric compounds

• polysulfide- errors and transition metal complexes, derived from polysulfanes
• sulfide errors, metal sulfides more content required
• bismuthate (include mixed bi oxides - structures etc ; sodium bismuthate(structure, indeterminate analysis of commercial product- mixture- ref said carbonate water etc contams

• Tool set
