The reaction of Cu(I)(CH3CN)4BF4 with 4-pyridylacrylic acid (4-HPYA) affords an unprecedented 8-fold interpenetrating diamondoid-like coordination polymer network [Cu(I)3(4-PYA)2(H2O)(BF4) ] (1) with a Cu+4(CO2)4 cluster as connecting node. The interpenetration in metal coordination polymers is the highest degree ever found within diamondoid nets containing a cluster as connecting note. Strong yellow-green fluorescent emission is observed for 1 at room temperature.
