Summary description: Hybridization diagrams for transition metal complexes
Announcement text:
----------------------------------------------------------------------
Subject: transition-metals
New release v1.0 – package for transition metal electronic configurations and
Hybridization diagrams for transition metal complexes
Date: 18 May 2026
We are pleased to announce the first release of the transition-metals package
for drawing hybridization diagrams of transition metal complexes.
Features
• Single command: \Complex{atomic
number}{metal}{charge}{ligand}{coordination number}
• Supports sp, sp², dsp², sp³d, d²sp³ hybridization
• Automatic distinction between strong ligands (low spin) and weak
ligands (high spin)
• First row (Z=21–30): depends on ligand type (NH₃, CN⁻, CO, en)
• Second and third rows (Z≥31): all ligands treated as strong
• Fills orbitals used in hybridization (d, s, p)
• Automatically calculates: d electron count, magnetic property
(diamagnetic/paramagnetic), EAN
Changes
• Renamed main command from \ComplexStrong/\ComplexWeak to \Complex
• Fixed Extra } error with \ComplexStrong{26}{Fe}{2+}{(CN)}{6}
• Added hybridization support for coordination numbers 2, 3, and 5
• Replaced \drawDElectronsPaired with safer electron drawing
Bug Fixes
• Fixed missing yellow fill for sp, sp², sp³d hybridizations
• Fixed incorrect electron configuration for elements Z > 36
Installation
tlmgr install chemhybrid (CTAN submission pending)
