CoordCheck: Expected-Fingerprint Sheets for Metal-Complex Synthesis

A tool for chemists to compare the measured properties of a new metal compound against expected values.

A bench tool that generates the expected diagnostic fingerprint (IR band positions, UV-Vis bands, conductance class, magnetic moment) for a planned metal-complex synthesis from curated literature series, then checks the chemist's measured values against it — turning a day of spectral interpretation into minutes.

Concept

After synthesizing a new metal complex, chemists confirm what they made by matching diagnostic signatures scattered across textbooks and papers. The new paper [0] shows how compact and decisive those signatures are for one family: reacting [RuCl2(PPh3)4] with macrocyclic Schiff bases in ethanol reproducibly yields octahedral, diamagnetic, non-electrolytic trans-dichloro Ru(II) complexes whose telltales are a vRu-N band at 500-520 cm-1 (coordination through the C=N nitrogen), a single Ru-Cl band at 300-320 cm-1 (chlorides trans to each other), UV-Vis bands at 460-520 nm and 280-290 nm (charge-transfer and spin-allowed transitions), molar conductance of 12.0-20.0 ohm-1 cm2 mol-1, and a magnetic moment below 1.0 BM. CoordCheck encodes curated series like this into a rule engine with one wedge — know what success looks like, then confirm it. Before synthesis, it prints an expected-fingerprint sheet for the planned complex (metal + ligand class + route). After synthesis, the chemist enters the measured IR/UV-Vis band positions, conductance, and magnetic moment, and receives a structured verdict on coordination mode, cis/trans geometry, electrolyte class, and spin state, with mismatches flagged (e.g., two M-Cl bands instead of one suggests a cis product). The launch catalog covers Ru(II) tetraaza macrocycles and grows family by family from the literature.

Why now

The new paper [0] demonstrates that these signatures are family-stable rather than single-sample anecdotes: all fifteen complexes across diamine chain lengths n=2-6 show the same tight ranges (500-520 cm-1, 300-320 cm-1, 460-520 nm, 280-290 nm, 12.0-20.0 ohm-1 cm2 mol-1, <1.0 BM) — exactly the regularity a rule-based expectation tool needs to be trustworthy. The paper also shows the full verification chain (IR + UV-Vis + conductance + magnetic moment) is a single routine characterization pass, so the tool's input form matches what a lab already measures the day the complex is made.

A highly focused, evidence-backed tool that transforms routine inorganic characterization from manual literature searching into a structured verification workflow.

Evidence strength
5/5
The full-text digest provides precise, consistent numerical ranges across 15 different complexes, proving the 'family-stable' signatures required for a rule-based engine.
Market pull
4/5
Precious-metal R&D labs (like Johnson Matthey) have high stakes in synthesis purity and geometry, creating a strong pull for a tool that accelerates verification.
Novelty & moat
4/5
While SpecHarvest extracts data, CoordCheck applies it as a real-time diagnostic tool for the bench chemist, filling the 'Synthesis-to-Property Mapping' gap.
Feasibility
5/5
The MVP is a simple rule-based lookup and comparison engine; no complex ML or simulation is required to launch the first catalog.
Wedge clarity
5/5
The focus on Ru(II) tetraaza macrocycles provides a sharp, narrow entry point to prove value before expanding to other metal families.
Simplicity / focus
5/5
The product is a single, clear utility—an 'expected vs. actual' checklist—avoiding the trap of becoming a generic chemistry platform.
