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.
To do list
In progress- awaiting RSC access to complete.
- silicon phosphate compounds /silica phosphate glasses
- BaPbO3 - used in lead acid batteries
- Bi2O4 - new article? or just a mention in Bismuth?
- plumbate - metaplumbate anion - - PbO32- - 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
- Carbonate missing solubility summary of salts, missing carbanato complexes (neutral and other), missing occurence of MIII 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
- gallium(I) oxide (suboxide) missing
- 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 CHn+ 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
- Axiosaurus talk page
- Draft1 oxidation state
- Draft2 gallium chalcogenides
- Draft4 thallium chalcogenides
