130 years after Mond discovered the first homoleptic carbonyl complex Ni(CO)4, we report on a [Ni(CO)4].+ salt as synthesis of any nickel cation in condensed phase. It was prepared by oxidation metal with synergistic oxidant Ag[F{Al(ORF)3}2]/0.5 I2 (RF=C(CF3)3) CO atmosphere. This D2d-symmetric metalloradical represents last missing entry among structurally characterized cations Groups 6 to 11....

This erratum is to correct the report of the crystal structure of strontium tetrafluoroborate (Bunič et al., 2007). The investigated compound was Cd(BF4)2 and not the reported Sr(BF4)2 because of experimental error. We report here the correct structure of strontium tetrafluoroborate, which appears to be isomorphous with the previously published structures of Ca(BF4)2 (Jordan et al., 1975) and C...

function f: G  , with this property that f(G1) = f(G2) if G1 and G2 are isomorphic. There are several vertex distance-based and degree-based indices which introduced to analyze the chemical properties of molecule graph. For instance: Wiener index, PI index, Szeged index, geometric-arithmetic index, atom-bond connectivity index and general sum connectivity index are introduced to test the perf...

A. Proof of Theorem 1 We first recall the following lemma. Lemma 1 (Lemma 1, (Gong et al., 2013)). Under Assumption 1.{3}. For any η > 0 and any x,y ∈ R such that x = proxηg(y − η∇f(y)), one has that F (x) ≤ F (y)− ( 1 2η − L 2 )‖x− y‖ . Applying Lemma 1 with x = xk,y = yk, we obtain that F (xk) ≤ F (yk)− ( 1 2η − L 2 )‖xk − yk‖ . (12) Since η < 1 L , it follows that F (xk) ≤ F (yk). Moreover, ...

In this paper, we study the boomerang spectrum of power mapping $$F(x)=x^{k(q-1)}$$ over $${\mathbb {F}}_{q^2}$$ , where $$q=p^m$$ p is a prime, m positive integer and $$\gcd (k,q+1)=1$$ . We first determine differential F(x) show that locally-APN. This extends result (IEEE Trans. Inf. Theory 57(12):8127-8137, 2011) from $$(p,k)=(2,1)$$ to general (p, k). then by making use its spectrum, which ...
